be interested in knowing what some of the equipment is on the engines particularly. For example the front lower sections vary a lot depending on where they operate. I have seen snow plows and cattle scoops and some with nothing like down here in Florida. Some of your photos show what appears to be electrical and hydraulic cables and connections and weird blades. I have designed the rail systems as well as spurs and service connections but know absolutely nothing about the engines themselves. If you can input on things like this I would appreciate it.
