After a recent visit to Shrewsbury, I noticed that semophore signalling was still in use, along with colour lights, so after returning home I decided to retro fit Dapol motorised LED signalling...here is phase 1 completed...installation of three signals and signal box, PLEASE NOTE, the line on the left is the bi-directional mainline out of Harold Station...the line on the right is also a bi-directional line in and out of a DRS depot opposite the station which crosses over further down the line...so please do not assume I've put that signal in the wrong way round...which some have...never asumme, just ask a question and I'm more than happy to answer it....👍
