I have just restarted my n-scale train activities after a 5 year lay-off. I find myself with a 2-8-2 USRA Mikado but don't know the manufacturer. The tender is hard wired to the engine and has pickups on the tender. I have a parts page but it dose not mention the manufactrer. My desire is for it to pull a few newly purchased Overland passenger cars which are new from Athern (Old Roundhouse) with knuckle couplers. The Mikado tender has a Rapido coupler and I wisch to make the tender and cars compatible as far as couplers. Anyone have a guess who made the engine and how I can get the right couplers on the engine or cars?
