tual complete conversion to diesel power, and set
up a procedure for strictly policing our own
smoke. Thus we were well prepared when the
anti-smoke ordinance came.
One day in February of this year, the Union
sent out 63 steam locomotives and 64 diesels, and
so for the first time may be said to have begun
more than 50 per cent diesel operation. With
other diesels on order, our program calls for 80
per cent conversion by the middle of 1950, and
complete conversion at a later date.
Within our work we must have different types
of locomotives for different jobs. The newest diesel
locomotives are Baldwin 1,500-hp road switchers
having 6-wheel trucks and 6 traction motors per
locomotive. These particular locomotives, because
of the traction motors and heavier weight, enable
us to pull four to five hundred tons more per train
and so release some of the larger steam engines.
The specifications of these diesels are given
on the opposite page. The design stresses sim-
plicity of controls. The speed of the locomotive is
controlled by the throttle only. The power plant
has automatic load regulation. The diesel engine
cooling is automatically controlled by thermostat.
