I have a layout working exclusively with servos. It has been in operation for over three years now and has proved very reliable. The only problems I have encountered were due to pilot error. All points, semaphore signals, uncouplers and even the shed doors are operated by servos using MERG circuit boards driven from a computer. I made my own servo mounts as the MERG items weren’t available at the time. I have found servos far superior to all other types of point control I have tried and very cost effective. The MERG circuits give adjustable travel and speed and can be set up for each servo in a matter of minutes using the free MERG software. Video and photos of the servos in use on the layout can be seen on our website http://a19modelrailwayclub.org/layouts/alwinton/
