Convert your freight and passenger cars to either rigid jaw couplers that mate perfectly with Micro-Trains Couplers or buy a new set of trucks or just truck frames with authentic Micro-Trains working Jaw Couplers.
All Con-Cor freight and Passenger trucks use an axle length of 0.560 +/- .005 inches. This has been true for almost 40 years, so you can convert any old-production Con-Cors by recycling your Con-Cor wheelsets and buying only new truck frames if you so choose.
