Please explain why a double ended unit needs to be turned especially
on a railway that would turn them with normal traffic anyway.
73 stock are made up of 2 3 car units making the 6 car train. *They are
handed; A ends and D ends (A are even numbers and D are odd numbers). *A
double ended unit can match with either but has to be coupled A to A or
D to D.
If one of the double enders that has been matched with a D end unit now
needs to be reformed to match with an A end unit it will need to be
turned first, hence the little trip to T4.

It is impressive to see how LUL saves depot space (?) by taking an
empty little train round a full trip, clearly wasting a lot of
electrical energy if I must say.
