Micro-Trains has produced a new and improved coupler for our 4-wheel and 6-wheel Commonwealth Passenger Trucks (also known as 1017 and 1018 trucks). This new coupler, which we’ll refer to as the 1017-2, is designed to reduce excess movement of the coupler in the box which provides better holding power when pulling longer trains. This coupler will be in all of our existing black and silver 1017 and 1018 truck packs, but it will also be sold separately.
