I replaced both the GP-20 couplers and the cement hopper couplers with Brit Kits replacement couplers.
My question is whether there's a separate coupler replacement for locomotives, since it appears an air hose on the coupler is duplicated on the engine -see "Brit Kit Replacements" showing the connections between two engines.
A separate thanks to Elphaba for the scenario "GP20s Battle Donner" which is shown in the attached screenshots. An excellent scenario, matching motive power and load.
Thanks,
Rob
