chiltern Mk3 DVT generator vans.

That's the one. Set AL04 was the first silver set to be sent to Doncaster for the power doors to be fitted. Set AL01 is also at Doncaster. 82304 is still under test at Wembley and should be ready to go with a loco to pick up set AL04.

So I take it, the sets are staying silver/grey??

 

[t_star2001uk]

As far as I'm aware that is the plan.

Great

So any pics of the work in progress for AL04?

With the Christmas break and delivery due in January - they must be nearly complete (if some coaches aren't aready complete).

So are these going over to DOO when the doors have been fitted then, or the pointlessly complicated procedure of Guard buzzes Driver who shuts doors so Guard can check doors then buzz Driver to start train etc..... Can't see the RMT being overly impressed

From the looks of it it will be driver releasing doors, guard closing. This is becoming the standard proceedure these days, and is actually quicker as the driver can release the doors as soon as the train comes to a halt, wheras the guard can often be slightly delayed (either just reaction time, or actually getting to a door to release). Also allows manual SDO to be fitted, wheras with guard operated doors automatic SDO is needed which is slower.

Why do they need a genny van when the skips are ETH-fitted?

These plug doors on the mk IIIs, I suppose you can't lean out of the window on them.

It's quicker on the release, but dodges a standard safety procedure of powered door stock. One of the primary reasons for the delay on Guard-operated stock is the Guard opening his 'local' door and checking that the train is platformed correctly, which safeguards against a stop-short and helps ensure that the doors are released on the correct side. A Driver sitting in a warm comfy cab is far more likely to release doors in error in these circumstances, but it appears this is another short-cut our modern railway is happy to take

We also have the marvellously convoluted Voyager method of dispatch, whereby the Guard has to press a button to tell the Driver to press another button to close the doors, despite the Guard being the one who is actually responsible for the doors but actually having no direct control over them. Hmm... :roll:

For station layovers when the 67 is turned off.

Are there any layovers long enough for that?

 

[Nym]

Also means that Non ETH AAR Locos can haul the coaches if needed...

[Nym]

Not push pull, but AAR Multiple Working is fitted to the DVTs, and through cabling to carrigaes.

During the normal weekday timetable the 2 silver sets (AL03, AL05) will stable in the sidings at Birmingham Moor Street and the Banbury commuter set (AL02) stables in the cattle road at Banbury. So to ruduce the amount of noise complaints and the amount of fuel used by having a 67 running with the HEP switched on for cleaning and train prep, we will use the generator which will not only provide hotel power for the train but will also provide air as well.

Unfortunately I am guessing you are right.
May be the way forward these power doors, and at least it keeps them in service for longer, but for me it makes them a lot worse. Why does a modern touch have to ruin things?!!!!

Yes he is right. The windows were almost triangular used on the trial doors, so assuming they've not changed that much, they still will be. Look very smart but the whole door is replaced. Certainly no drop-light!

Would it be possible to make a power door with a drop-light? I suppose since the railways doesn't like passengers sticking their heads out of windows anymore there wouldn't be any point in one anyway.

 

[Pumbaa]

I doubt it heavily - there is no need as the doors are automatic, and they are thin.

Well quite. Absolutely no need; whilst the risk is small from drop lights it is real so might as well eliminate it.

Cl442/5WES units have such a droplight IIRC, I believe to provide ventilation should the air conditioning break down, or simply because the door panel was a standard SR part, them being insanely frugal.

 

[Hydro]

Droplights are extra maintenance, people leave them open, letting in draughts and water, they leak and let the draught in easily enough as it is.

 

[williamn]

The 442s have opening windows in their doors but they're locked shut.

They're for emergency use by the guards only, though I have seen people open them with the lid of a biro in the past!:roll:

Doesn't look like it.

They seem to be one of the best ever kept secrets in the rail industry.

 

[asylumxl]

There was a photo in Rail magazine a few months back (quite a few months back I think), but I don't think anyone has posted it online.

 

[Pumbaa]

The prototype was pictured in Modern Railways.

Do we have a release date yet for set AL04??

First set now not expected out of Doncaster till towards the end of March
