I've managed to build the platform starter for the Up line following the description of making a tubular post signal in Mick Nicholson's Constructing and Operating Semaphore Signals (Booklaw publications 1999) I'm pretty pleased with it, particularly the coloured 'Crystal Klear' for the lenses. It still needs the lamp fitting which is why you can see the colours from the rear. Operation is via a servo controlled using a MERG servo4 card (which also gives me bounce).

Having positioned the signal I got to think about the starter on the down line. This is on the inside of the curve and would actually be positioned off scene as the platform curves around to the left in the photo below. As such it would probably have had a sky arm so that it would have been visible above the canopy for an approaching train or, and this is the fun bit, could well have had a repeater signal, probably located almost opposite the signal box just in front of the driver in this picture.

I seem to remember an article or drawing about constructing a repeater signal, can anyone remember where?

thanks
