Signalling – below the baseboard with Martin Lloyd

Whether you build your own semaphore signals or use ready-to-plant products, you still need a reliable and affordable operating system to make them work.

Martin Lloyd will take you through the benefits and drawbacks of the many options available, from shape memory wire to Fulgurex/Tortoise-type motors. Far and away the best results, he’s found, come from using servo motors controlled by a simple electronic device and this is what the course will concentrate on. If you want to stick with rheostats and wire-in-tube for the rest of your layout, that’s fine – here Martin will show you how to build servo mounts, attach them to signals, test their effectiveness and finally drive them using the latest Servo4 technology.

SignalThe course is emphatically not about building the signals themselves, but with acquiring the knowledge to make informed decisions about signal operating systems. Martin’s experience of installing the signalling on Roy Jackson’s epic EM gauge Retford – and latterly his own group’s vast South Pelaw layout – enables him to deliver practical, hands-on answers to the many questions modellers have about what goes on under the baseboard.

Of course you can’t really model signals without having at least some idea of how the prototype works, and this is something else Martin will be touching on. All railways had different practices and the study of signalling procedures is almost a hobby within a hobby. If there’s a particular type of signal that you’re interested in building, Martin will be happy to discuss this with you beforehand and to suggest areas where a little preparation in advance of the course will help you get the most from the weekend.
