PROTOTYPE RAILCAR 50,000 FITTED WITH
ROLLS-ROYCE 8 CYLINDER ENGINE AND TORQUE CONVERTER.
1 MOTOR CAR AND 1 TRAILER CAR.
With reference to the notes of the meeting held at the British Transport Commission on the 9th May, 1958, I have now received an estimate from Messrs. Rolls-Royce for the modification to the control wiring and equipment to make the prototype eight-cylinder cars Nos.50,000 and 56,000 so that they will be miscible with B.U.T. gearbox cars. Their estimate is for £600 and the total estimated cost for the conversion of the cars including the work that will be necessary in Derby C. & W. Works will be £2,500.
This embraces the following :-
New Control Desk and Controllers required.
(B.R. to supply all equipment).
Pneumatic Equipment on underframe to be changed to that the car is the same as B.U.T. cars.
Two B.U.T. type throttle controllers to be supplied by B.R.
Relay Boxes and E.P. Valve Boxes to be changed. Watch panel to be removed. Start isolation box to be changed.
Plug and Socket connections to be provided on engines.
Final Drive Switches to be changed.
Jumpers to be changed to English Electric Co.'s type. Extra train wires will be required.
The various alterations to wiring and air piping will probably mean that some of the existing installation will have to be changed.
