Hi, I have nearly finished a scratch built 5 Inch gauge riding truck, which I intend to use with a 5 inch gauge diesel loco. I want to put some brakes on the riding truck. I was intending to scratch build them, using brake block castings acting on the front and rear wheels of two four wheel bogies. The problem I have is finding enough information, i.e., dimensional drawings, brake layout etc to help me do this. I would appreciate any help or advice about the best way to go about this.
