I've built a few Great Western wagons over the years and the weirdo brake gear has always confused me. Normal brake gear I understand, push the lever down and the brakes come on. If there is a clever cam arrangement then the brakes come on on both sides.
Dean-Churchwood brake gear seems a lot more complicated and drawings didn't really explain it to me. My solution has been to build normal wagons with normal brakes. Even the GWR eventually saw sense after all.
Last week however, I had the chance to photograph a DC fitted wagon at the Severn Valley Railway. The vehicle is mostly missing a floor which makes the light a lot better for taking snaps. Best of all, I remembered how to use the panorama function on my compact camera to capture all the action.You might want to click on the image to see the details.
It still looks over-complicated to me. If anyone can explain the benefits, I'm all ears.
