Railroad equipment manufacturing: same structure as machinery
Manufacturing rail cars and locomotives uses the exact same cost structure as machinery & industrial equipment manufacturing - frame fabrication, structural welding, and drivetrain/electrical assembly.
Same structure as machinery manufacturing
Manufacturing rail cars and locomotives - body frame fabrication, structural welding, drivetrain/electrical assembly, paint finishing - uses the EXACT SAME ten-category structure as Machinery & industrial equipment manufacturing. There is no unique unit, no unique formula branch, and no cost item this industry has that machinery manufacturing doesn't already cover.
See the Machinery & industrial equipment manufacturing guide for the full ten categories: materials (steel plate/bar by weight), equipment (cutters, welders, typically owned), labor, scrap, consumables, subcontracted work (bought-in electronics/engines), rework, packaging, freight, overhead.

A machine is an assembly of made parts, bought parts and subcontracted parts, each costed differently. How to roll them up, where the double count hides, and why commissioning is a cost line.
