With the roof, stairs and glazing complete, the finished signal box was put into position at the end of the platform at Brookwood Station.
Before doing so I made a plinth for it to rest on, which also serves as a barrier to keep things dry.
After programming the decoder (55025) via the LGB MTS Programming unit (55045), all four pre-cabled switches/points were tested. Once tested the plinth was screwed onto the base.
