As these giants sit there unattended, their massive engines churning over and relief air valves cracking off on several locations on all three units. Equipment like this seem far more alive then mechanical devices. This was also the case with the old steam locomotives which would shudder and lurch about while parked. The Diesel-Electric locomotive is a relatively new machine in the railway industry. The first one to come through my home town was as late as 1959. With in a few years the black monsters of the steam era disappeared rapidly as they were phased out and piled up in stacks at IPSCO in Regina to be melted down and made into steel pipe.

The image above is of the air control system, the bell on the upper right is located under the locomotive. Below are some of the connections as can be further seen on the right.
