1972 tube stock. How rare is a train without a middle driving cab.

I think it’s my first time seeing one and I regularly use the Bakerloo line.

Train 3299

Train 3299

There is only one. The four-car unit is made up from cars salvaged from collisions.

Unit 3539-4539-3439 was withdrawn as a result of a buffer stops collision in Harrow & Wealdstone siding, while unit 3257-4257-4357-3357 was withdrawn as a result of a derailment at Piccadilly Circus.

Cars 3357 4357 and 4257 were mated with 3439 and reconfigured to form unit 3299, with an UNDM instead of a DM at one end.

Meanwhile cars 3257, 3539 and 4539 were scrapped as a result of the damage they sustained.

So train 3299 is coupled with other 3 cars units as usual. But the main difference is that the four car unit doesn't have two cabs like other 72 4 cab trains.

Correct.

Does it handle differently, does anyone know?

Wouldn’t have thought so. It does have its own specific mention in the stock training though, as clearly the lack of a middle cab means certain equipment and operating differences.

Think 3399 has basic controls for shunting in depot.

How does that work? So there is no cab but it still has basic controls? Where do they put the controls when there is no cab and the passenger doors are where the cab would be? I would be curious if anyone has a photo?

It has an UNDM car, which contains the shunting controls. So instead of the train being formed DM-T-T-DM+UNDM-T-DM, it is instead formed DM-T-T-UNDM-UNDM-T-DM.

The key difference is that the unique UNDM on this unit is wired to face the opposite way to normal, in order to stand in for a DM car.

As it’s not mentioned in this thread:
UNDM Uncoupling Non Driving Motor
T Trailer
DM Driving Motor

same equipment fitted to:
C Stock (only upon refurbishment)
D Stock (without DBVIC)
1973 Stock (similar)

Took a snap of the shunting cabinet on the 73 Stock for comparison.

(Picture shows a 1973 Stock shunting cabinet with controls such as whistle, selector switch, traction brake controller, and various reset buttons.)

When driven from the 72 stock shunting cab, how does the driver look ahead? Their body will be in front of the shunting panel, while their head would be leaning over the window on the centre door?

Correct, as happened with unrefurbished 1973 and D Stock.
