inside coal hoppers

[NW Modeling List]

Thanks for the follow-up, Ken. If I’m interpreting this correctly, recently rebuilt cars that received new steel would be primed on the interior, but not finish painted (whereas new cars got both). That’s an interesting - and curious - detail.

However, when repainting hopper cars which have had no new steel applied, the inside painting is to be omitted if the corners and crevices are still properly protected. Under favorable drying conditions, the first coat of paint can usually be applied over the primer after two hours.
