WTT 70 & Hainault to Woodford Shuttle

That was a very useful issue for me. I used it to plug the draft coming through the M door this morning. Worked a treat.

None, because the 1992 stock is made up of 2 car units,

This will make my routine travels to and from Roding Valley very interesting. Potentially, there will be a better frequency in the morning peaks if the timetable spaces out the shuttle services more evenly with the direct services to and from Grange Hill.

goldenarrow There are four more A-B Units than B-C Units. Meaning that you could take four 8 Car Sets with intermediate cabs and split them to have two 8 Car sets with no intermediate A-B Units and four 4 Car sets.

I look forward to the passenger reactions when they realise that capacity has effectively been halved. Though I doubt that there will be shortage of seats on the Woodford - Hainault Section, I personally think it's a sensible measure. 

Squarewheels says there are shunting controls on both B and C cars. Like most unit trains, the necessary equipment for a unit to function is shared between the cars in the unit, and as I understand it the C cars carry the same underfloor equipment as the A cars (other than the cab). I can't find a reference to which equipment is carried by the A/C cars and which by the B cars, except that:
1. a London Underground information sheet says that there is only one static converter (auxiliary power supply) per two car unit (but doesn't say which car it is carried on)
2. some C cars have de-icing equipment fitted (these cars being known as D cars). Note that this means that a four-car train cannot include a de-icing car, which may make things interesting on the Woodford/Hainault shuttle in the winter if this WTT is implemented.


The same sheet says there are actually ten more A cars than C/D cars (175 to 165) so you could potentially make up to five four-car trains. (In practice four, if you don't want to be left with an odd half of an eight-car train (A-B + B-C).) However, I understand some of the A units now have to run in the middle of trains because of various faults in their cabs, which would need rectifying if they were to be used at the outer end of a train.

Paper airplanes!


Leave the cab and the shunting panel is at the end of next carriage, next panel is on car diagonally opposed etc. etc. so, shunting panels on all cars except A cars

Wouldn't be too certain

So with a fleet that is already struggling for reliability and whIch rarely provides the number of trains needed for the peak service, they are looking to make further increases to the service?

I get that NF, but an extra 8 car train still won’t cover the seemingly regular peak cancellations due to non availability of stock.

I just don’t get the logic behind it.
“We’re struggling to run our current timetable. I know, we’ll create an even more demanding one. That’ll do the trick.”

There are no plans for that and it would probably be an operational nightmare.

No chance. Assuming any spare stock was available, it would have to be compatible with the Central line ATP system. Converting anything else would require money and training of staff to drive and maintain them. It’s also undesirable to have more than one stock operating on a line.

sorry, I made a typo, I meant North Acton or White City - not Ealing Broadway!

You have to disband an 8-car set to create two four-car sets, so you only free up one eight-car set.
