    How high is Reading Viaduct?

    Starting at a point approx 320m West of Reading station, the line climbs at 1 in 93 for 536m, then 1 in 730 for 548m, then descends at 1 in 85 for 611m; not including the transitions between different gradients. Total rise in track level is approx 5.75m

    Opentraintimes IM86??

    Probably the signaller’s shorthand for Item 86

    Poor regulation decisions at Rugby?

    But that’s small picture thinking - the gaps you want to slot trains into at Rugby, don’t exist further up the line where LNWR services also need to join the UF. If late 9R20 was slotted behind 1R22 out of order (and even later), then 1Y16 and 1W18 are sat on the US at Ledburn without a path...

    Poor regulation decisions at Rugby?

    The flighting of trains into Euston in the morning peak is deemed as critical - that’s why all AWC arrivals into Euston have a 1Rxx/9Rxx train description in ascending order. There probably are get out clauses that once a train is X minutes late the in order rule is suspended; but it is...

    Differences between TPWS, ATP and ETCS

    To answer the OP - all 3 do basically the same; but offer improving levels of coverage. With TPWS the supervision is non-continuous - in simplest terms the train gets checked against a set speed at set points along the track - those checks normally only taking place when the signal they apply...

    Differences between TPWS, ATP and ETCS

    With ATP the release speed is set by distance to a theoretical conflict point beyond the signal. That distance is passed to the onboard computer at the previous beacon/loop, and the train then works out a safe speed for that conflict distance. I don’t believe it is intelligent enough where a...

    Reading - Paddington route set for overhaul - BBC report

    I fear a couple of things from this:- 1) Funding. As the article says, this is all being done from Western Route’s existing budget; which is cut vs previous budgets, and significantly so if you factor in inflation and the like. Whilst the problems are most acutely felt in the inner Thames...

    Landslip in Sonning Cutting

    In the practical sense there is likely to be some disruption tomorrow. The original estimate, when the work they’ve been attempting (unsuccessfully) today was going to be done yesterday, was the main lines would be handed back but with emergency speed restrictions and blocks to electric...

    Heathrow Airport & Crossrail - Longer Platforms?

    At a Civils Level, CTA and T4 are probably fairly easy; as you say there’s a level of pre-construction done. T5 is probably too constrained - all stemming from the construction methods used and the continued passive provision for future infrastructure immediately west of T5. T5 is basically in...

    Up through line at Newbury

    Me too, unfortunately I have no idea why it hasn’t been sorted yet.

    Up through line at Newbury

    In the early part of the year, flooding at Newbury damaged various bit of signalling equipment. The Up Through line has been out of use ever since.

    10 Car v 9 Car IET Staffing

    The points at Bourne End are NOT signaller controlled. They can only be operated from the Ground Frame at Bourne End, with a single line token withdrawn. All trains using Platform 1, must have a guard. Passenger or ECS, regardless if they’re going to/from Marlow or not. DOO operation is only...

    North Downs Full Line Closure 10th Feb to 18th Feb

    It was 165117 rescuing the stranded 165118. There were a series of 3Zxx route proving trains, the last of these round trips was commandeered to go recover 165118.

    10 Car v 9 Car IET Staffing

    It has to be a “GWR” driver (in terms and conditions sense), rather than old HSS/West T&Cs. West of Didcot is outside DOO “area” so yes guard required.

    10 Car v 9 Car IET Staffing

    From a train dispatch perspective they’re guard-operated Bourne End <> Marlow, DOO Bourne End <> Maidenhead. However, If a train (either passenger or ECS) has a need to operate to/from Marlow platform at Bourne End, even if it is running Maidenhead to Bourne End only, it must have a guard to...

    10 Car v 9 Car IET Staffing

    IETs can only run DOO from stations with staffed dispatch - ordinarily Paddington, Slough, Maidenhead, Reading, Didcot, Oxford and Banbury - and only when the whole scheduled journey is/was entirely within the DOO area (Paddington to Banbury/Bedwyn). Part DOO is authorised for trains meeting...

    North Downs Full Line Closure 10th Feb to 18th Feb

    I suspect it’s a hangover schedule from when cycling units that way was the plan - the gauging issue has not been resolved. If it were ad-hoc organised it would be a VSTP not an STP schedule.
