This steam locomotive, number 2634, is a Canadian Pacific
Railway 4-6-2 Pacific type, class G2s. Ahead of the stack rests an Elesco feedwater heater. It was not
original equipment, but was applied during a later rebuild. The purpose of this device is to use exhaust steam from
the cylinders to pre-heat fresh water going into the boiler. Most North American steam locomotives built,
or rebuilt, after 1920 were equipped with feedwater heaters. Several common types were in use such as the Elesco, the
Worthington ( usually side-mounted ) and the Coffin.
