The 4D has the numbers and coding:
6000T - 5000M - 5002M - 6002T

>From the Addenda to the Working Timetable:
=====================================================================

M - Electric Multiple Unit Motor Carriage
T - Electric Multiple Unit Trailer Carriage

A Driving compartment is located in the M class car, expect in the case
of the Double Deck (4D) train which has the Driving compartment located
in the T class car.

=====================================================================

For the same reason 6001T and 5001M were not used the computer with all
the fleet information on it can handle only 3 car trains and the codes T
and M.  

(the 4D train is treated as M - 6000T - 5000M - 5002M - 6002T - M, and I
think the phantom M cars are 6001 and 5001 or something stupid like
that.  I think the Harris Greaser is treated as 794M - T - 797M with the
T car being a phantom.)
