Converting an Athearn RS-3 into a Montreal Terminal RS-3m (MTRR calls it a RS-251r, but railfans call it a -3m) by cutting off the cab & short hood and replacing them with a cut down RS-11 high short hood and a RS-32 cab. It came as L&N 123, but it’s going to end up being MTRR 10001 after the cement has cured and I can clean up the seams and fill in the gaps.
(I need to redo the MTRR roster to better represent my evolving headcanon for what my model railroad operates.)
