I've always enjoyed watching the sequence of setting equipment on, or getting it off rails. Boxcab E50
In this era of computer control and laser range finders... ... it looked pretty "low tech"... eyeballed!
Here are some interesting photos I took as CSX was recovering from Hurrricane Katrina. New ties were being unloaded from a 7 car train pulled by this "locomotive". The tie train from a different angle. Picking up the old ties. There's nobody in the truck....the crane operator is the only one on the job and he's controlling the truck. Lastly, two crews welding both ends of a rail inserted as a patch.
