Diesel Locomotives of Sri Lanka

Construction of Class M7

1981 “BRUSH” diesel engine of Sri Lanka.

CAB CONSTRUCTION

This page shows the cab construction of the M7 project.

The full size cab has two driving positions, on the left-side looking forward along the bonnet and directly in the opposite (right) corner looking over the battery box compartment. The cab body also incorporates the dynamic brake section in the recessed bit just in front.

It is proposed to install a plug in control point on both buffer beams so that this engine can be driven from either end without the need for using a turntable. Just like the real M7 it can run round the carriages and hook onto the other end of the train.

There are no plans at present to do anything inside the cab. This floor area sits directly above one of the main stretchers that carry the bogie mounting pivots. Once one bogie has been made and fitted with its drive system and motor only then will it be possible to envisage what clearances will dictate and any obstructions or unused space be known.

Each bogie has to be able to pivot and move without fouling the cab floor or adjacent area’s. The frame width inside has been determined from measurements taken from sketches and should allow enough clearance where required.

The hood of the battery box compartment is removable so that a heavy duty electrical isolating switch can be fitted to allow quick disconnection to occur if need be.

Working lights and horns will be added after the engine has been track tested and deemed fit for duty.
