jasp Posted October 24, 2019 Share Posted October 24, 2019 I know that the 1923 spec. required brakes to be able to be applied from both sides but did the spec. require brakes on all four wheels or just two on one side of the wagon?

Barclay Posted October 25, 2019 Share Posted October 25, 2019 They don't need to be on all four wheels. The Morton brake in unfitted form has only 2 shoes on the same side. It has a clutch device which enables the lever on the non-brake side to operate the brakes. This entails a shaft passing underneath the wagon to connect the two sides. This I believe is why most mineral wagons had simply 2 separate sets of brake gear, one on either side, as the Morton system's shaft would have fouled the bottom doors.

That's not correct. Brakes were required to be applied from either side. So wagons with bottom doors, for instance, were allowed to have two independent sets of brakes.

Il Grifone Posted October 29, 2019 Share Posted October 29, 2019 The brake had to be able to be applied from either side and also released from the same side. The GWR Dean-Churchward brake failed to meet this criterion, as it could be released from either side as well. Many wagons previously had only a set of brakes on one side only. The easiest way to update them was just to add a second set of brake gear. The GWR at least were not above adding a second brake that only operated on one wheel.

RMweb Premium Compound2632 Posted October 31, 2019 RMweb Premium Share Posted October 31, 2019 Furthermore, the requirement for a brake that could be applied from either side and released from only the side on which it had been applied was a Board of Trade regulation of 1911, so the RCH 1923 specification is only relevant to this discussion insofar as it was a standard that embodied this regulation. Would the RCH have been involved in discussions leading up to that regulation, as a representative of the railway companies? Link to post Share on other sites More sharing options...
