96 Stock and D Stock Enquiries

[bb21]

Does Jubilee Line stock contain a half-unit 96075 96275 96675 96475?

It is in my record from the weekend (96075) but the asset sheet from a TfL FoI request shows no sign of it, with the highest numbered half-unit numbered 72.

Secondly would anyone be able to find out the half-unit D stock that formed a train with 7026 on Saturday (27th)?

Help appreciated. Cheers.

Yes, the Jubilee has 96475-96675-96275-96075 an east/south facing unit.
Units are numbered:
east/south
96001 odd to 96125
west/north
96002 even to 96126


7026+7537 on T011 on Saturday 27th.

Marvellous. It was indeed train 11.

In terms of East/West DM/UNDM designations, do these ever get turned around?

I have something from a couple of years ago which suggested that 7511 is the leading (DM?) vehicle in a formation on an Eastbound train, while 7510 is the middle vehicle. The asset sheet from TfL reveals that currently 7510 is the DM in the half-unit while 7511 is the UNDM.

In addition, what happens with Piccadilly Line's 1973 stock, when the whole unit runs around the loop at Heathrow Terminal 4, and East on the previous journey becomes West on the following journey?

 

[Dstock7080]

On the District, Bakerloo, Jubilee, Victoria, W&C trains cannot be turned in normal circumstances, so would stay - north/south, east/west. If District trains are turned, they very quickly get them turned back.
The Metropolitan, Central, Circle, Northern, Piccadilly all have loops and trains are fully interchangeable.

Double-ended units: D Stock/'73 Stock, have no favoured end, they can work at any end of a train- to replace either a west or east facing unit.

Ah, excellent. Cheers for that.

Finally, if you don't mind me asking, what happened to 72 stock's 3299? It no longer appears to be on the asset list.

I saw unit 3299 only a couple of weeks ago. Couldn't see which 34xx it was paired with unfortunately.



By the way... one can avoid a lot of confusion with those double ended 73 Stock and D Stock units by cheating a bit and using their centre vehicles as the "describer", in your case above that would be 17510...

3299 can and frequently does work with any unit from 3531 to 3567...

It is rather a pain to shunt though...

Isn't it traditional to use the lowest numbered vehicles as the unit describer ( except for my "cheat" where some are double ended, as above, I generally stick to that convention )?

And yes, I can imagine 3299 would be awkward to shunt - is it done with a radio link between a pilotman and a driver?

It has always been customary on LT/LU to identify 2 unit trains by the leading car number, irrespective if the inner facing DM has a lower number;
i.e.. A Stock 5016+5057 (although middle DM was 5056).

You can drive any 1972TS Mk1 or Mk2 unit from either end (provided its Mk2 Refurbished).
There is a shunting panel provided in the No.1 cabinet of each UNDM (3399 and 34xx cars)

 

[Peter Mugridge]

Just to confirm, 3299 is still in traffic; I had it for haulage today and it is paired with 3467 at present.

There is no reason for 3299 to be taken out of traffic for anything other than planned maintenance and changes, has been with 3567 for a while now though.

Routine maintenance is roughly the same as any other 1972TS MkII Unit...

I was responding in the context of bb21's query a few posts earlier about it not being on the current asset list.

Right-o, well it's definately in the asset database, perhaps someone transposing it onto the asset list messed up?

 

[bb21]

Is there a reason why it is numbered differently to the others?

It's formed out of an incomplete unit and a Mk. I UNDM (Uncoupling Non Driving Motor) that was refurbished to the same standard as 3465 - 3467 rather than the usual
DM(R) - T - T - DM - UNDM - ST - DM(R).

The wiring is the same as a standard '33' car at the coupler though, so it can couple of any '34' car.

It's formed of;
DM(R) - T - T - UNDM - UNDM - ST - DM(R) when in formation with a 3 car unit.
But it is not wired as an UNDM, it is wired as a standard DM of that end.

It's quite a good unit to get northbound from Waterloo as the extra set of doors ( where there is a cab on all the other units ) lines up exactly with the exit at Baker Street...
