As somebody more interested in the signalling and control side of railways (I taught computer networking at University, which has many common features with railways) than scenics, I have been looking for controllable signals. I have used the Dapol 4L-002-001 signals in the past, but they have a major problem: their initial state is not guaranteed. This is a shame for automation, as the construction would make adding feedback a trivial, low-cost addition.
I am now trialling the servo version, which is better suited to automation, and the bounce is a nice feature - but it would be good to have a means of tuning it.
This is a brilliant accessory, easy to install with minimal wiring for a simple power supply, looks really authentic, is well lit and has a brilliant, adjustable, action giving great realism, including a "bounce". It is totally complete with all the switches needed for really easy installation and is without a doubt the best signal I have ever installed.
This is my fifth Dapol servo powered double signal. All have been easy to install and programme. The train tech controllers likewise have performed impeccably. I would heartily recommend them to any Model Railway enthusiast.
