Greenwich couplings - CPL-10a Standard

Contents: 6 pairs of couplings, including 3d body, etch, pivot wire and iron wire

The Greenwich Coupling is not a completely new invention but rather an improvement on the systems that were available at the time. Unfortunately we are no longer able to get the brass blackened.

These Greenwich Couplings comprise a 3d printed body and etched brass loop. They are designed to plug into standard NEM 355 sockets provided on ready to run models from Bachmann and Peco. Two versions are available to cater for the different manufacturers to ensure a consistent coupling height. The loops are cut out from the etch and folded into the correct shape and this takes a moderate amount of modelling skill. A folding tool has been designed to ease the folding process and improve consistency. The printed body and etch are connected by a bent brass wire pivot. A small amount of iron wire (provided) is wound around tail part of the coupling loop that protrudes backwards at an angle. This lifts the coupling open when moving over a magnetic field, either permanent or electromagnetic.

Small permanent magnets for use as fixed uncoupling positions on a layout are also available.

These couplings are designed to plug-in maintaining a constant height across the Greenwich Coupling range. Also available is a coupling height gauge so that you can fix your couplings to a consistent height above rail level ensuring that all your stock can couple up.
