On the central line this morning I saw a 6 car 92 stock train with 2

an amalgamation of spare cars perhaps?

Sounds normal to me.

The 92TS comes in two car units, with a cab at one end or no cab, just a
shunting control cabinet. Are you saying you saw a cab in the middle of
the train? That would be quite within the standard permutations.


Yes, four two-car units in every train, all fully reversible and able
to fit anywhere in the train.

A rough count suggests that there are 175 units with a cab and 165
without a cab, so there are bound to be some with cabs in middle
positions.

The 3rd cab wasn't in the middle, it was 2 cars from the end. Hence the
subject line. I'd not seen that configuration before - they're usually in
the middle.

Why are there extra cabs anyway? The 92 stock was always going to be 8 cars
everywhere AFAIK. Are they just spares in case of failure?
