Alan I will borrow one of the pins tomorrow. We are running our outside track at Kew Bridge Steam Museum http://www.kbsm.org/ this weekend (a superb museum by the way). I will be there in the morning. I will take a pic as well and email it to you. I would love to find a source for more. No one seems to know where we got them from. We do check the bracket as well as it was actually the bracket that caused so much hilarity so many years ago.

Both seem to vary widely between clubs. As for accidents. I was visiting one club once when the coupling parted and the loco took off like a scalded cat. It managed to stay on the track until it collided with another train. Upon checking, it wasn't the coupling that had parted, but the bolts holding the bracket to which the coupling was secured. Said bracket was only held on by two 4BA brass bolts. Luckily damage was minimal, and no one was hurt. alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. ----- Original Message ----- From: "Peter J.

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. Peter MODEL ENGINEERING DISCUSSION LIST.
