Asengines of different lengths are to be test-ed, and of necessity have to be fixed atthe trailing end to the dynamometer, it isnecessary to have a sliding chimney forcarrying off the steam and smokefrom the engine when running. Thishas been provided in the form of along box, having a steel plate running onrollers forming its lower surface, whichplate carries a large bell mouthed chim-ney.

Thislatter device enables the speed oi the en-gine to be set at any required number ofrevolutions and kept constant. 3. The carrying wheels are 4 ft. 1J-2 ins.•diameter. The main bearings are 14 by 9 ins. diameter. The tire of the■carrying wheels is turned to approxi-mately the same section on the tread asthe rails in use on our line. This plantis intended not only for the purpose ofscientific experiment, but also to do awaywith the trial trips of new and repairedengines on the main line. It has. there-fore, been necessary to make it rapidlyadjustable to take engines having wheelsof different centers. The main bed is ing.
