Making the semaphore style signals on your layout operate just like the real thing is often a costly process, requiring the use of a rather price point motor for each signal you wish to automate. But it doesn’t have to always be that way, as Brian will show us here in this excellent tutorial he’s sent in. Always keen to make use of recycled electrical components and other resources, Brian got his thinking cap on and came up with a somewhat lower cost solution.
I am very keen on making my own models using recycled materials where possible.
The relay contacts may be used to isolate a section of track in front of signal so that the train may only proceed when the signal is down.
Pic 1 shows relay with side casing cut away and operating wire soldered on. This pushes lower quadrant signal into the down position, for upper quadrant signals invert the relay before fixing.

Well, thank you Brian, for sending this brilliant tutorial in… I’ll be keeping my eye out for an old PABX unit now! As always, if anyone has and questions, comments or suggestions for Brian, please feel free to post them via the comments forms below and we’ll pass them on to Brian.
