Greenwich couplingsCPL1 • by G&DNGRS
Contents: 5 pairs of couplings, including pivot pins 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. This includes developing a process that blackens the brass fret so that it does not require painting after being built (apart from the occasional touch up). This means that paint is not clogging up the moving parts.
The Greenwich Couplings come as a black brass etched sheet kit. The couplings are cut out and folded into the correct shape and this takes a moderate amount of modelling skill. A small amount of iron wire (provided) is wound around a part of the coupling 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.
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.
