I have a drawing of the chopper couplings as fitted to the Lynton & Barnstaple locos. It (the drawing) looks like a p/copy of a p/copy (several generations !).

PM me an address & I will put a copy in the post.

hook coupler

Is the hook coupler you are looking for the same as those used on the Indian railways 2' gauge railways? I forget the true name of it, but I remember the name being unusual.

Indian Hook coupler notes

Post by Loco112 » Sun Jul 13, 2008 9:15 pm

from IRFCA website;

The Jones coupler (an adaptation of the Norwegian coupler) coupler is used on some MG and NG lines. Also known as the "chopper coupler", this uses a hook (the chopper) which fits into a yoke on the coupler of the next car. A bar behind the yoke controls the tension in the coupler. MG wagons and coaches have a the chopper at one end and the non-chopper coupler at the other end, hence a rake of MG wagons has to have them all oriented in the same way.

Jones couplers were developed in India and later spread to several east African and south-east Asian railways. Some NG lines still use a basic Norwegian (or 'chopper') coupling, which has a square or circular face with a slot coming down about half-way from the top.

The Darjeeling Himalayan Railway uses a rudder coupling system to deal with the severe curvature on some sections of its route. However, the Kishanganj branch of the DHR used chopper couplers, as can be seen on the DHR C class Pacific at Mumbai and the lone Garratt made for this line.

"grandsire" take a look att this link and tell me if this is the coupler you are looking for; http://www.narrowgaugetalk.com/anyone-i ... -t279.html
