Had both the 4 wheel and bogied IoM coaches. Worked ok through LGB 45 mm/code 322 stuff. Both R5 and R3 pionts. Fitted as standard with Accucraft's chopper couplers. There are 2 heights for coupler fitting marked on the coach ends.One is the standard height for most stock, the other to match the higher coupler location on their IoM locos. Max
