Cambrian Railways Station Lamp Name TRENCH HALT. Original name that would have been mounted within a Platform Lamp, this one has been mounted on an actual size piece of glass in the form of a Lamp Tablet. Trench Halt was on the line from Ellesmere to Overton-On-Dee in Shropshire and closed in 1940, re-opened in 1945 and finally closed in September 1962
