This might be the last styrene underframe I ever do. There are two reasons: first they didn’t actually paint underframes, even on passenger cars. Second, making styrene look like wood is a nuisance, but making wood look like wood is a doddle. So the next project is going to try a wooden underframe again, and I’ll paint all the hardware before installation rather than after so I don’t have to deal with that either.
Even so, I think this is turning out reasonably well. You’ll have to wait until the lettering goes on to see the sides.
