A One Industry Railroad Operation

[nachoman]

My narrow gauge railroad only serves a copper mine and its associated company-owned town. I think that qualifies as one industry.

Inbound:
Raw materials for town and mine construction
machinery/tools
coal (for the smelter)
firewood (for the town)
people
food
chemicals

outbound:
copper and other mined metals
people
miscellaneous refuse (other smelter by-products)

Comparing to your Kraft list above, your plant may irregularly receive machinery or other raw materials related to the plant upkeep and maintenance.
