Suggestion: I worked with an in-law briefly (labor guy) on weekends at place that might work for you. There was no rail involvement; flat beds would bring in sheets of stainless for laser cutting on a rather large "table" that was computer controlled. You could pull this off by combing a couple of the structures.
The rail work could be done outside under a canopy: Inbound steel plates in gons that would be lifted out by a magnetic overhead crane (somehow it doesn't lift the car) then moved inside the building for the cutting. Outbound shipments of boxed items in box cars from a loading dock on the side (with some trucks of course), and the scrap being accumulated and loaded to gons for remelting with new steel. Some inbound drums and pallet boxes in box cars as well.
As I recall, the outfit was Washington Steel, the cutting location for some reason was in Frazer or Malvern, PA.
