Alan We use bars, as probably most clubs do. As for pins, we have a set of pins with a spring semi-circle which is quite vicious if you're not careful. It means, however, that once the pin is in it simply can't bounce out. This is critical. All locos are meant to be checked by the loco super for the day to make sure the couplings are totally secure. We have a video taken probably 20 years ago, by pure fluke, of a loco on the track with the loco parting from its driving carriage. We play it occasionally on club nights and it brings tears to the eyes! On the more serious side it made us realise what can happen and that is why we sorted suitable pins. Hilarity is the mother of invention.

The most common one that I have seen is the flat bar, with pin dropping in hole in bar and into brackets fixed to each vehicle. However, the size of bar and pin seems to vary. Has anyone any information on couplings? What does your club use? What is used in other countries? alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. MODEL ENGINEERING DISCUSSION LIST.
