The Westcott Engine Museum, which is situated in Chapel Lane, Westcott, on the A25 about three miles from Dorking, will be open all this weekend. Examples of early engines, incuding probably the only running order Priestman engine in the world will be on display, and pretty much all the engines will be run at some time or other over the course of both days. I think there will be some signposts, but it's not actually a very difficult place to find-just ask any of the locals!
