The small size and controllability of servos makes them an attractive option for turnout control. NIGEL BURKIN experiments with a Heathcote Electronics dual servo motor board, turnouts and a hand full of servos.
SERVOS ARE growing in popularity amongst railway modellers for the control of a wide range of animated effects, including working semaphore signals, level crossing gates and barriers to name a few.
Turnout or point control is one of the applications for which low cost micro servos can be used to great effect. With several ‘tight’ locations to contend with on my layout where slow motion turnout machines such as the Tortoise or Cobalt are too large to fit, a different approach was required. Micro servos and the Heathcote Electronics servo motor controller offered a possible solution.
