December 2014 TT changes

[infobleep]

The same way they cope now - they use SDO (front 7). I can't see why UDS would be a problem, it isn't a problem anywhere else.

UDS is unit deselect, the simple form of selective door opening LM use where you can open only the doors in the units forward of the cab you are in.

I expect the reason peak services do not call is simply because they are already overcrowded without adding Wembley passengers to the mix. There might also not be room in the peak timetable for it, as more trains run than off-peak.

I'm sure that will be the case during the peak. During peak time most trains towards Euston run late from Harrow or they did last time I worked around there.

Of course numbers of trains running won't be an issue on Sundays.

Wembley to Tring? I think not.

Big flow right there.. :roll:

What does UDS stand for?

In addition to what Neil has said above, SWT's Desiros also use Unit Deselect - I'd have thought you might have seen it in operation when long trains stop at Clapham Junction P7?

Which reminds me, I wonder what ever happened to SWT's ASDO project...

 

[TEW]

ASDO is now not expected to go live on SWT Desiros until some point in 2015.

I thought South West Trains only opened the doors in blocks of 4 or 5. Surely that isn't the same thing as unit deselect. After all I thought Southern wasn't constrained to 4 or 5 block openings of doors.

The blocks of 4 cars (8 doors) being an entire 450, and blocks of 5 cars (10 doors) being a whole 444, yes? Counting from the front of the train? It is most definitely unit deselect. It is fairly logical that the 350s carried on the same system as the 450, because they are from the same original order.

Your right though in that Southern are not so constrained, because their trains have individual carriage level ASDO already, and have had for a good few years, many from delivery.

 

[HarleyDavidson]

ASDO is a complete nightmare,reading the ASDO manual is scary! Still can't get my head around some of it,at least I won't have to worry about the 458 derivative as 458 traction has now expired!

 

[SprinterMan]

I see the old WAG2 has picked up an annoying 17 minute wait at Crewe to let 1D93 1910 London Euston to Holyhead, presumably as a quid pro quo to Virgin from Arriva in return to letting 1D31 1650 Manchester Piccadilly to Llandudno run ahead of 1D90 1610 London Euston to Bangor between Chester and LLJ. This was not the original plan, as 1D31 was originally going to wait at Chester to let 1D90 pass, but instead it runs ahead and does not call at Flint.

It is held at Crewe to replace a withdrawn 21 00 Crewe to Chester as part of massive changes on the North wales Coast to provide additional capacity. There are numerous changes to calling patterns.

Ahh, so it was. How I missed that I don't know. Thanks very much

Should be Monday 16 February unless the operators have a dispensation (perhaps for a football match) and covers Network Rail Period C in Section 4 of Rules of the Route for Galton Street Jn to Wolverhampton Crane Street Jn for 21:30 Monday to Thursday nights to 05:30 Tuesday to Friday mornings.

What work is happening for the route to be blocked?

The difference is cause by the manufacturer. Siemens never introduced carriage level SDO where Bombardier did. Not 100% sure why. The Desiro City fleets will have same sort of SDO as the Electrostar fleets.

Perhaps to be a touch pedantic, Electrostars & Turbostars do. Some, such as 8-coach 455 formations on the Horsham-Dorking route, need coaches to be locked by hand & checked. This is permitted and done every weekday.

Agree, but I was responding to the point infobleep made where he was comparing SWT and SN's different approaches to SDO - which by implication only concerns the units that actually have SDO.

This original discussion took place in mid December, and I still can't quite see why 377/5 needed to bump it just to state the obvious, that Siemens and Bombardier used different technology. Again, that much was implied by the earlier contributions.

I hadn't noticed that that part of the thread was that old compared to the more recent comment that had put the thread back up to the top.
