Lovely example of a Winson 14xx! I'm curious to know whether the axle pump works on this model? I've been having a lot of problems with mine as it almost locks up when I turn it on, reducing the locomotive power.
Hi Laurence, yes the axle pump works, i ran for almost 3 hours using just the axle pump. It sounds like ur delivery is possibly restricted somewhere causing a back pressure? Looking at the pipework on this its 3/16 pipe, not sure if thats std size or a modification. Its certainly very efficient and effective when running, it does knock the pressure back when its on, but fills quickly.
Thanks Lee! I'd never considered that the piping could be the problem... It's quite likely, considering that the original owner seems to have done a bit of a bodge job on most of the piping! Does it reduce the pressure as much as the injector, or is it more efficient?
Laurence I’m no expert, but I think that the axle pump reduces pressure more, because it constantly pumps cold water into the boiler, but more slowly. Injectors are quicker, and the pressure rebuilds quickly once turned off. For me it usually depends on how strong the fire is.
Thats a very sweet running locomotive thnx for posting
Great stuff. Glad you're posting again.

The larger the pipe diameter, the more water that can flow through which will reduce the back pressure from the pump.
