In answer to the query in the previous post, a quick primer on wagon brakes with diagrams nicked from gwr.org
Below is what most would consider the standard (Morton) British brake system. Three basic types: double acting with a cam on the shaft to cope with the fact that the levers are both at the RH end. Independent as per wagons with bottom doors. i.e. no connecting shaft as per the Airfix mineral wagon kit. Fitted, with the addition of a vac' cylinder.
The above is the Dean/Churchward as fitted to the Coopercraft range of kits with a short lever on each side at the same end. These were considered non standard and were sometimes replaced with Morton types during upgrades post 1930s. As always a multitude of exceptions within all this.
I remember building a Ratio kit with Morton brakes when I was about 13, the moulding of the cam that reversed the action of the "other" lever fascinated me.
ReplyDeleteThank you Chris. I must admit that this is an area little explored by Yours Truly. Isn't this what The Web is all about, or should be?
