Great Western Electrification Progress

[GRALISTAIR]

Good shots thanks. Looks like quite a lot of bespoke bases and thus masts for this part of the project.

 

[Mollman]

Still cannot reconcile changing over from electric to diesel to electric in such a short distance with all the potential problems of starting up Diesel engines from cold . Roger Ford says the drivers are having to change over manually (BOTTOMS) as the balises cannot be trusted ? Also, drivers of the 387’s could forget just the same and go through Steventon above 60 mph . Best interim solution would be to place a 60 mph blanket speed limit on all traction until the issue of the bridge was resolved ?

I read Roger Ford's comment as the section being too short for balises to be used rather than them being untrustworthy.

So the last approx 500m of wiring west of the point I photographed is a waste of infrastructure then? - aside from the fact it may be a pan-up/down area for through trains?

I thought it had been explained it ran far enough beyond the station to allow 387s to reverse? Did I imagine that?

 

[Thatcham Xing]

Did I imagine that?

No you didn't - another reason why this section surely needs to be powered?

 

[swt_passenger]

Found it now, post #7444 etc, early August.

No, it's not a waste - we aren't in the habit of putting wires up for no reason. It is overrun protection - in the event on an IET not panning down at Newbury Racecourse for some reason, it will guide the pan safely through Bartholomew St and Rockingham Road overbridges without damage to train or infrastructure. Plus if the wires are ever extended beyond Newbury, everything is capable of conversion to live with minimal effort.

You've hit the nail on the head there, @GazK.
This logic is the exact same reason why parts of the Windsor, Colnbrook & Marlow branches are wired, why part of the Basingstoke line is wired, why part of the Golden Valley Line from Swindon is wired, and why part of the Cross Country route from Westerleigh Junction is wired.

 

[3973EXL]

Parapet work on Butts Hill Rd, over Sonning Cutting, has finally been completed.



Southbury Lane Ruscombe, parapets completed over tracks, wing walls still incomplete.

It was pure waste in case of the "overrun protection" on the unelectrified Goblin line at Gospel Oak in London. When the Goblin line was electrified recently, the full length of the overrun protection at Gospel Oak was pulled down, including the substantial masts & scrapped. All new equipment was put up.
Not unreasonable of Thatcham Xing to suggest the same at Newbury.

 

[Meerkat]

That’s really attractive.....not!

 

[59CosG95]

Give it a few years and exhaust fumes and mud from the passing cars will turn it as brown as the surrounding bricks again.

That all makes sense, but so did the earlier explanation that 387s would be able to reverse west of the station. Presumably that was posted with the best intentions at the time.

Indeed, I'm fairly sure whoever originally posted it did so under the assumption that that is what would happen. I'm not so sure on its likelihood now that the OLE to the Limit of Wiring has been proven to be a Neutral Section (ba-dum tss).

 

[Thatcham Xing]

No, it's not a waste - we aren't in the habit of putting wires up for no reason.

Ok, and apologies to GazK for flippancy - I wasn't in the best frame of mind when I wrote about the "waste of infrastructure"

Out of interest, I noticed on Saturday (when there were extra services due to the Newbury Races) that a Turbo was reversed at Newbury (from the down to the up main platforms) by bringing it back "wrong side" to a signal just west of the Racecourse, and then it reversing and running back into the Station, crossing at the points that are used to get to the up side just east of the Station.

I guess EMU's could be reversed this way?

 

[Mag_seven]

Apparently Swindon-Didcot is barred to electric traction this week - anyone know why?

 

[FGW_DID]

Apparently Swindon-Didcot is barred to electric traction this week - anyone know why?

Engineering work on the OLE.

 

[ArchieWoodbine]

Apparently Swindon-Didcot is barred to electric traction this week - anyone know why?

As FGW_DID mentioned: engineering work. More specifically, it's pertaining to preperations for the energisation of Cocklebury sidings this weekend (07:00 09/12/18).

No offence taken - I guess I'm a little defensive as a result of the "everything about GW electrification is BAAAD" attitude which is popular in some quarters... (but not here)

Cocklebury sidings, being near Chippenham (yes?) had me puzzled at this explanation. Could you possibly expand please?

 

[3973EXL]

Cocklebury sidings, being near Chippenham (yes?) had me puzzled at this explanation. Could you possibly expand please?

No. Just east of Swindon station on the up side (north). Stabling for 387 units as Maidenhead sidings are Tfl, and there are no wires to Oxford. Swindon was chosen over Didcot I believe.

GWML Electrification: State of Play, as of 3/12/18.
All mileages given from Paddington, except where noted.
Paddington to Wootton Bassett Jct - LIVE

• All main line tracks wired as far as Wootton Bassett Jct, and are to be considered "live" as such. The envelope of "live" wires continues along the South Wales Main Line to Filton Jct (inc. Bristol Parkway), and to the Limits of Wiring on the Berks & Hants line and Reading-Basingstoke Line; details are given below.
• TTCs have replaced/been replacing headspans at various locations within London - locations include Westway (beneath the A40), Acton Main Line, Ealing Broadway, and between Southall & H&H. These are part of the works for the Elizabeth Line.
• Everything wired at Reading (bar P4-6 which were never in the plan). Includes the TCD & the curves, down to Reading West (see B&H section).
• West of Didcot Parkway, all lines are wired & live heading towards Swindon.
• Everything wired at Swindon (bar the goods lines north of P1, where provision is provided).

Small Points

• ATF wires in operation from Maidenhead to Wootton Bassett; Kensal Green to Maidenhead currently only using return conductors but will be AT-ready in the near future. Some AT wires up along this stretch now; whether they are live remains to be seen.
  • In preparation for the Elizabeth Line running to Maidenhead, Hayes & Harlington to Maidenhead was closed off over the Early May Bank Holiday (5/5 to 7/5); this included renewals of S&C at West Drayton & Slough West Jct, alongside HOPS work at Langley. Paddington to H&H was also closed on May 6th, and encompassed final OLE works for Crossrail, alongside (presumably) ATF installation, finishing of Platform Extensions, lift shaft installation, passenger footbridge installation, and ticket hall foundation installation.
• At Ealing Broadway, the staircase to P2/3 has been demolished and replacement with a new structure as part of the Crossrail works is now underway. Access is via the footbridge at the London end from P4 - work started on 1/10 and should continue until late December.
• Parapet Work complete at Southbury Lane Bridge, Ruscombe; the wing walls remain unfinished. Original Coping stones have now been replaced.
• At Butts Hill Rd Bridge, Woodley, metal screens have now been affixed to the outside bars - meaning works are now complete.
• Platforms are being extended at Cholsey (country end), Goring & Streatley (London end), Pangbourne (country end), & Tilehurst (1 & 4 country end; 2 & 3 London end).
• Few masts and cantilevers now up on the Didcot Avoiding Line, which finish at Appleford; Appleford LC being the limit of wires for the time being.
• Oxford Lines west of Didcot Pkwy wired as far as the loco fuelling sdg; Down Oxford as far as 53m 31ch, Up Oxford as far as 53m 42ch. Didcot avoiding lines have sprouted masts (4 portals, 2 TTCs), with a wire pair over the Down Didcot Avoider.
• A note on Steventon: Wires up under the High St Bridge (aka the "Brunel Bridge"); however, the bridge may well be demolished in CP6. "Temporary" parapet work to protect passers-by from stray currents now complete. Wires west of Causeway Crossing are onnowy authorised for passenger service on 80x trains in both directions; the discussion continues.
• Overruns through Swindon Jct (77m 36ch) onto the Golden Valley Line have also been wired.
• Another note on the OLE beyond Didcot: the wires west of Causeway Crossing were authorised for passenger service (as of Sunday 28th October) as far as Swindon for Down (westbound) trains, with the Up line following 2 weeks later on Remembrance Sunday. Trains may run on AC under test conditions (as ECS) beyond to Wootton Bassett & Bristol Parkway, but entry of IETs in AC passenger service beyond Swindon is unlikely before December.
• Electric Traction is barred from running between Didcot & Swindon this week (3/12 to 9/12) as preparations for Swindon Cocklebury Sidings going live for EMUs are finalised. The sidings are due to be energised on 9/12 at 0700hrs.

The "Main Line"; Wootton Bassett Jct - Chippenham (Cocklebury Lane Bridge)
Until further notice, the 25kV transmission wires will run in a trough from Cocklebury Lane Bridge (just east of Chippenham) to Thingley Jct. Large steelwork is expected to remain in situ until wiring is authorised west of Thingley, but some specific items may be poached if required elsewhere (and duplicates aren't stored at RAF Wroughton). Details given in the "Postponements" section.

• All masts and earth wires are now up between Wootton Bassett Jct & Cocklebury Lane Overbridge.
• The Up Line is wired throughout from Cocklebury Lane to Wootton Bassett.
• The Down Line is fully wired apart from a gap in both catenary & contact wires adjacent to the site of the former Dauntsey station, no bigger than 200m.

Chippenham (Cocklebury Lane Bridge) - Thingley Jct

• No piles in Chippenham station, nor any masts affixed to the viaduct.
• All piles in and majority of masts (and cantilevers) up from the western end of the viaduct to Thingley Junction (where the feeder station will be). Most TTCs have booms from beyond the viaduct to Thingley East Junction. About 14 masts are up in the vicinity of Thingley Feeder Stn, 2 of which have TTC booms affixed. Another has an STC boom.
• Piles continue westwards to the next bridge.

Thingley Jct - Keynsham

• No wiring for the foreseeable future, but overbridges between Thingley Jct & Box Tunnel have all been rebuilt. Corsham Main Road Bridge needs its parapets raising. New aqueduct & footbridge at Corsham complete.
• Both Box & Middle Hill Tunnels have had track lowered.
• A new footbridge has been built at Ashley Box.
• Piles also in (and have been for over a year) at Ashley (beyond Box Tunnel) - these might well be trial piles.
• Bathampton Jct to beyond Sydney Gardens has had track lowered. A new signal gantry at Bathampton Jct was installed over Xmas 2017 but is not yet in use.
• Bath Spa platforms realigned & raised, with track also slewed.
• Track through Oldfield Park & Keynsham now lowered.
• A lot of piles are in along the embankment around Saltford and Keynsham in readiness for future wiring.

South Wales Main Line (Wootton Bassett Jct-Bristol Parkway-Severn Tunnel-Newport-Cardiff)

Wootton Bassett Jct to Filton Jct (inc. Bristol Parkway) - LIVE

• All catenary & contact wires up from Wootton Bassett Jct, past Westerleigh Jct (107m 14ch) through Bristol Parkway and thence to Filton Jct & Stoke Gifford IEP Depot; Chipping Sodbury Goods Loop and the Cheltenham Curve overrun (as far as the limit of wiring) are also fully wired and live.
• BPW Platforms now fully wired; includes the Down Goods Loop & Up Passenger Loop.
  • A number of masts & booms (now all wired up) are up on the line towards Filton Abbey Wood, between Stoke Gifford Jct No.1 (111m 79ch) and Filton Jct No.1 (113m 01ch); these end just short of Filton Jct 1 and will presumably act as an overrun until electrification continues into Temple Meads.
  • Section Isolator Masts now installed immediately before Stoke Gifford Jct No. 1, for the proposed neutral section just west of Bristol Parkway; these now have their feeder wires.
• Filton Bank bridge works (mileages all from Temple Meads):
  • Easton Rd Overbridge (1m 18ch) completely rebuilt.
  • Narroways Footbridge (2m 12ch) replaced.
  • Ashley Hill Footbridge (3m 11ch) replaced.
  • Bonnington Walk Overbridge (3m 62ch) - parapets raised.
  • Footbridge south of Filton Abbey Wood (4m 18ch) will need work if wiring is to occur.

Filton Jct - Severn Tunnel

• The Patchway/Severn Tunnel Blockade is now complete.
• The 3-week Bristol Parkway Blockade and subsequent weekend blockade are also now complete.
• Stoke Gifford IEP Depot all wired.
• Patchway Tunnels conductor rail installed.
• Masts, booms and SPS up through Patchway. No wires yet.
  • Cattybrook Brickworks Bridge closed as of 18/3/18.
• At Pilning, during the Summer Tunnels blockade, all portals and masts have now been erected, and wires have gone up (west of the station). Earth wires and C&C wires are now up eastwards from this wired section, through the station, to the split-level section before the Patchway Tunnels. The Down line is fully wired here, while the Up line still needs finishing work in a few places.

Severn Tunnel - Newport
Due to have IETs in AC service by 2020!

• Severn Tunnel Conductor rail in place. A number of masts on both sides of the line are now up at Caldicot, just before the Western tunnel mouth; these now extend westwards towards the eastern end of the platforms at STJ.
• Part of the central island platform at Severn Tunnel Junction has been fenced off - a possible mast location?
• All bridge rebuilding complete from Severn Tunnel Jct (149m 14ch) to Bishton Flyover (152m 30ch).
• Masts beginning to go up between Severn Tunnel Jct & Bishton Flyover, as of 3/4/18. These include:
  • At least 11 between Undy (Church Rd Bridge) and the M4 viaduct over the mains; one just east of the "white house" has a TTC boom. It can be assumed that its 8 comrades will be similarly adorned. Another mast over the Reliefs west of the "white house" has now gained a TTC boom with 1 SPS assembly; it has a twin over the Mains.
  • Two opposing pairs of TTC masts have gone up between Church Rd Bridge & the Playing Fields Footbridge.
  • Two large uprights have gone up between Undy Playing Fields footbridge & "the ramp" bridge at Magor on opposite sides of the line; these may well take a portal boom.
  • Another 3 masts (two for a portal boom, one a TTC with boom up) have appeared east of "the ramp" bridge at Magor; these join the sole TTC on the Up side by the bridge.
  • 3 of the 4 TTCs west of "the ramp" bridge (2 on the Down side, 1 on the Up side) bear SPS; a 4th TTC has been boomed on the up, opposite the more western boom on the Down side.
  • The signal gantry at Magor (west of the West End Footbridge) has been replaced by 4 signals on posts; this should mean its removal prior to electrification is imminent. A TTC with SPS is up over the Mains there too.
  • 1 mast is up to the west of Redwick Rd Bridge (by the Down Relief), and a mast due to bear a portal is up to the east of Whitewall Footbridge (by the Up Main). OTP is in place for a piling/masting operation by Redwick Rd compound.
  • One 4-track portal is up between the A4810 and the bridge over the eastern end of Bishton Flyover.
  • Masts (with SPS fitted) up between Bishton Flyover (including over it) and Llanwern West Jct (156m 20ch). 5 masts are currently up on the curve down from the flyover at its eastern end.
  • Plenty single masts (with SPS fitted & folded) up along the Mains between the Flyover and Bishton LC. A run of Earth wire is now up on the Up side at Bishton.
• Between Bishton LC (153m 01ch) and Llanwern Golf Course, masts are around 90-95% up (all bar a few have booms and SPS), with the main gap at Llanwern Works East Connection (153m 05ch). This continues west towards Llanwern Works West Connection/Llanwern West Junction (156m 03ch to 156m 20ch). 4 masts (3 over the Mains, 1 over the Reliefs) also have booms & SPS immediately west of the LC.
• A run of Earth Wires & ATF wires have been strung up on the Relief side (adjacent to the DR) between Llanwern Works East Connection & Llanwern West Jct.
• In this stretch also, wires are now up on the Mains:
  • 3 runs on the Down Main (one with catenary & droppers only, and 2 full runs of C&C to the west);
  • 3 run of Catenary & contact wires on the Up Main.
• Some masts have sprouted near Lliswerry pond.
• 6-track portals, probably TGBUs (aka Thumpin' Great Big-Uns) going up aroung East Usk Yard (approx. MP157 1/2).
• Between the Maindee Jcts (157m 74ch to 158m 16ch), a cluster of piles is in beside the Down Relief; these are complemented by masted piles on the Main side (adjacent to the Up Main).
• Caerleon Rd Overbridge to be refurbished in 2 phases - 20/7 to 30/11, and then January ‘19 to March ‘19. Not sure what impact on wiring this will have.
• Some SPS has now gone up between Maindee West & Maindee East; between Maindee West Maindee North Jct (41m 03ch from the former Rotherwas Jct, just south of Hereford; the ELR for the southern part of the Marches Line), masts with TTCs on are also going up (as overruns) over the Marches Line; the termination mast & associated TTC are just north of signal "NT 1559".
• Fixings for masts have now been installed on the Usk Bridge.

Newport

• All canopies now cut back.
• Masts and portals now appearing at the western end of the station, some with SPS attached. More started to appear in mid-April; additionally, two at the Cardiff end & two through the P1 canopy on the weekend of April 28th/29th.
• 4-track portal now up over the southern 4 tracks, just east of the new station footbridge.
• Two six-track portals have now gone up over the western throat of the station, just short of a 4-track portal (uprights of) & a TTC (with SPS) adjacent to Clytha Park Rd.
• Old stn footbridge now removed; 4-track portal of the "TGBU" (Thumpin' Great Big 'Un) variety has been installed in its place.
• A new portal has gone up at the east end of Newport, with all the fixings for switchgear affixed at the top. Droptubes for registration arms are also on.

Newport - Cardiff

• Plenty masts up around Gaer Jct (159m 32ch) north of Cardiff Rd Bridge (the B4237):
  • one by the Down Relief;
  • two by the Up Main (one of which is a boomed TTC with SPS);
  • three by the Gaer Jct - Park Jct Chord.
• Around 6 piles are in adjacent to the Up Main between Gaer Jct and Ebbw Jct (160m 07ch); these will probably take masts for portal booms. One such boom appears to have gone in! Currently unknown if Alexandra Dock Jct Yard will be electrified.
• Lots of steelwork up immediately behind the signal gantry adjacent to the Up Main at Ebbw Jct; this includes a full portal boom and a TTC acting as an overrun mast on the Ebbw Vale branch.
• Over 100 masts from Ebbw Jct to Marshfield (163m 60ch). Booms & SPS starting to appear in the area too.
• Green Lane Bridge, nr Marshfield (164m 57ch) reopened to traffic after reconstruction. Masts (with SPS) up around here too.
• Lots of masts (with booms, SPS & ATF brackets) now up near Mardy Rd Bridge, Rumney.
• Two TTCs, one on each side of the tracks, have been erected by the bridge at Rhymney River Bridge Jct (167m 61ch).
• About 4 or 5 portals have been erected just west of Pengam Jct (168m 40ch); 5 masts are up on the Up side east of Rover Lane bridge, complemented by 2 on the Down side. Some of the portals now have booms, and bear SPS; one of these has all its registration arms up.
• First Welsh Wire Run: 1 run of C&C has gone up between Moorland Road Jct (168m 65ch) and Long Dyke Jct (169m 35ch) over the Reliefs on the 15-16th September 2018; this is assumed to be a crossover as it crosses from one Relief line to the other.
• A handful of masts are also up around Long Dyke Jct; some have now gained TTC booms and SPS as well.
• Substantial mast foundations have appeared at each corner of the bridge over St. Mary's Street in Cardiff, along with work behind the nearby OU building. Masts may be imminent.
• Similar bespoke mast foundations are going in just east of Bute St Bridge, near the junction with the line from Queen Street.
• Splott Rd Bridge upgrade work now complete.

Cardiff Central - Platforms 0-4 to be wired

• Re-signalling completed. Platform 0 now open. 3 masts now up over P0/1 with TTC booms.
• Piling underway at the extreme ends of P1/2 & P3/4 for future masts. One can assume portals will bridge the gap between P2 & P3, over the Through lines.
• Canopy cut-back work now underway on P2.
• Brackets appear to be in place on the coping stones on the Taff Viaduct (at the western end of the station).
• Plenty piles up adjacent to Cardiff Canton.
• Brickwork Sidings to be increased in length (and electrified) to accommodate GWR Class 387s.
• Proposed Limit of Wiring: Leckwith Loop North Jct (171m 55ch) at a guess.

Swansea IEP Depot

• New IEP Depot at Maliphant Sidings, Swansea now complete; all steelwork up but no wires.

GWML/SWML Blockades:

• 6/7 to 3/12: Reduced capacity between Newport & Cardiff Central while electrification progresses; assume only 1 pair of lines open at a time. Done.
• 15/9 to 6/10, and 13/10 to 14/10: Bristol Parkway blockaded to allow OLE to be installed within the station; done.
• 27/10 to 18/11: Filton Bank blockaded for 4-tracking; done.
• 11/11: Bristol TM to Bath Spa blockaded until 13:00 while the resignalling work is completed on this stretch; done.
• 24/11 to 25/11: Filton Bank blockaded for further work to the 4-tracking; done.
• 1/12 to 2/12: Filton Bank blockaded for further work to the 4-tracking; done.
• 9/12: Bristol Parkway blockaded.
• 16/12: Didcot Parkway blockaded.
• 25/12/18 to 1/1/19: Bristol Parkway - Newport will be blockaded again, due to electrification work at Severn Tunnel Junction.
• More Blockades will follow; details as they become available.

Berks & Hants Line (Reading-Newbury) - LIVE
Electric trains are set to be in squadron service from January 2019 - ORR sign-off due around Christmas.

• Wires from Oxford Rd Jct are now LIVE to the limits of electrification (53m 42ch on the Newbury Lines, 38m 07ch on the Basingstoke Lines) as of 0650 on 21/10/18.
• EMUs to Newbury on test have begun! 800002 left Newbury on the AC over the weekend - 387s will begin test runs on weeknights from 3/12 (this week). Platforms will need to be gauged for other EMU classes.
• Within Reading West, piles for the new footbridge (under Murphy's remit) are in, but have been "decapitated" (i.e. shortened) and capped until a new footbridge solution is found.
• Extension to Reading West Up platform nearly complete. A new camera of sorts has appeared, and new station signs (GWR-style) are waiting to be erected.
• Parapet work now complete on the A4 (Bath Rd) overbridge. Similar works for Tilehurst Rd overbridge are now underway; the bridge has now been reduced to single-lane working for road traffic.
• Platform extension works complete (and now opened) at Theale, Aldermaston and Thatcham.
• Newbury's new footbridge is now open - are the lifts now working?

Limit of Wiring: 53m 42ch.

• Gives Ample room to reverse a 12-car 387 formation.
• Immunised signalling continues to about MP55 1/2. Bedwyn Turnback Siding now extended to accommodate 5-car IETs.

Project Postponements

• Thames Valley Branches: Windsor & Henley deferred to CP6. Marlow removed from scope of current programme. The first few yards of each branch (bar the Henley Branch) have been wired as an overrun.
• Southcote Jct to Basingstoke has also been deferred to CP6.
• Appleford LC to Oxford paused; if CP6 accounts allow for wiring to be extended to Oxford, it would be very likely to happen now that Oxford has been remodelled.
• Catenary & Contact wires between Chippenham (Cocklebury Lane Overbridge) & Thingley Jct have been deferred until (presumably) CP6; presumably this will wait until Bath-Bristol resignalling is complete. All Large steelwork to remain, unless required elsewhere.
• Bristol Temple Meads to Bath & Bristol Parkway paused, dependent on Bristol resignalling (Taunton-Parkway over Easter 2018, Temple Meads to Bath in November 2018 - both done), track remodelling and Filton Bank 4-tracking (underway - to be completed by December 2018).
• Bristol Temple Meads' "Midland Shed" to be reopened in CP6, after Bristol resignalling is complete and the PSB is demolished.

As always, do let me know if I've missed anything!
(apologies to anyone who saw it in a state of source code chaos too).

 

[HowardGWR]

No. Just east of Swindon station on the up side (north). Stabling for 387 units as Maidenhead sidings are Tfl, and there are no wires to Oxford. Swindon was chosen over Didcot I believe.

Ah, led astray by Google Maps, so I was! Thanks. (There is a Cocklebury Lane near Chippenham, where work is also taking place).

 

[Steve Tasker]

Rail mag has posted that GWR is delaying its’ introduction of new Hitachi trains on stopping services to Newbury and Berwyn until further notice. New CCTV cameras will have to be fitted so that the drivers can see when doors can safely be closed. Longer 9 car Hitachi trains on the route to the South West would be unaffected as they carry guards and do not stop at small unstaffed stations in Berkshire and Wiltshire.

[Pedantry]It's only the Bedwyn services that are affected; the Newbury stopping services (which terminate at Reading except in the peaks) are in the hands of 387s. The Bedwyn services only call at Theale & Thatcham west of Reading, so they'd be semi-fast to Newbury.

Besides, the CCTV cameras themselves are adequate - their protection (or rather, lack of) against railway grime and muck is the problem. I suspect some sort of "mudguard" similar to those fitted to Southern's 377s may be in the offing.[/Pedantry]

I guess I won't be riding them to work next month then

If they stop at Newbury on a loger-distance InterCity service, then you might do, but they won't be calling at Kintbury, Hungerford or (possibly) Bedwyn until the CCTV issue is resolved.

False.

They can stop at any station if they have a guard, it is the introduction on DOO services to Newbury and Bedwyn that has been suspended.

Apologies for getting my facts muddled @JN114! When I referred to those stations, I meant "in regular service", as the DOO services between Newbury & Bedwyn are the main ones that use them AFAIK.
