Does anyone have a drawing any scale, of the quarter turn steam valve that was fitted to BR Std locos to control the steam operated cylinder drain cocks.

Thanks, Howard

You may find one of the drawings in the xxSL/SW 1093 range may provide the details.

Not dimensioned, but labelled sections of both the drain-cock and the operating-valve in the Handbook for Railway Steam Locomotive Enginemen, British Transport Commission, 1957. There is very little text with it, the diagrams being sufficient.

It's quite an elaborate device considering it simply sends steam to the drain-cock itself, and releases it on closing.

I've scanned it and would include it here if I had any idea how!

Thanks Brian and Nigel, I have a BR Handbook for loco men so will have a look.

Kind regards
