In the Great Western Railway Magazine (March 1910) this
photograph of the gas engine and generator at the new Tyseley Engine Shed,
together with the following article regarding the motive power for driving the
machinery:
'In designing the depot the idea was to have an outside
electric traverser and an inside electric overhead crane to feed the lifting
bays. As, however, it was found that the greater portion of the other machinery
could be driven economically direct from the gas engine, thereby saving the
cost of electric conversion, it was decided that the generator need only be of
sufficient power to provide current for the traverser and overhead crane and
one or two machines situated some distance away. The gas engine was therefore
arranged at one end for direct driving on to the shafting by means of a
friction clutch pulley, and at the other end for operating the generator by
means of a jaw clutch and flexible coupling, admitting of the generator and
machinery being run either separately or together as desired.
The gas engine made by Messrs Fielding & Platt of
Gloucester, is a 200 BHP machine of the two cylinder horizontal side by side
type and can be run on either Town or suction gas. Although the cranks are in
line, the arrangement is for one impulse at each revolution. The generator was
supplied by the Phoenix Dynamo Manufacturing Co of Bradford. It is one of their
open, compound wound, multipolar , direct current type, capable of developing
75 kW (100 BHP) 250 volts. The motors taking current from the generator range
from 8 to 40 HP.'
