What I thought would be a bit tricky and take time, was simples. The four signals needed a touch-in of the paint work, putting on bases and the ladders added (one of the semaphore assemblies fell to bits, easily fixed with a bit of glue and a couple of spare bits I had).
Here they are just out of the paint shop...
and they are now in position on the garage layout as starter signals at each end of the two stations; the semaphore levers work manually....
