Locomotive brake valves / handles

[ntypeman]

Hi all...

Does anyone know if there is just ONE type of train brake valve type (I'm asking about BR locos here, NOT modern privatisation types)???

By that I mean is the train brake valve / handle on say a Class 87 the same as that on say a 47 or 50 etc...

I'm also after similar information on the locomotive / straight air brake valve if anyone can assist please???

Many thanks

Eric

No, the largest 2 different manufacturers of braking systems are Westinghouse and then D&M.
E.g. 33 uses D&M, 31 Westinghouse, 73 D&M etc.

Thanks A340...

I'm particularly interested in the Westinghouse brake handles... Its a long shot but does anyone have any further information or drawings / dimensions of them???

I doubt there are dimensions on there but could I suggest you visit 'Dawlish Trains' website and click on 'The driving cab', it should be of interest to you

Ive seen that site... The main reason I want dimensions is because I'm trying to model a representation of the brake valve...

Eric. As highlighted beofre there are 2 main manufacturers - Davies & Metcalfe (now part of Wabtec Faiveley) and Westinghouse (now part of Knorr Bremse). When a loco was designed and built (almost) all of the brake components for it would be from either D&M or Westinghouse. The systems genreally work in the same way but the componets are often very differently shaped.

If you are talking Westinghouse, then it is either an M8a (as found on a Class 37 etc ) or M6a (as found on an 08 Shunter for example. In ae30egkk's photos, what you see is just the handle portion of the M8a and the 'Straight Air Brake' by the side of it Are you just needing dimensions of the visible handle or of the whole of the M8a Brake Valve. I can supply you drawings with some dimensions on. The same goes for the loco/Straight Air Brake.
