Hello all, Here is a small review about the motorization of 9V switch points prepared originally in French for friends from Freelug. With the help of Didier Enjary for translation, Gaël Frazier for a final proofreading and Jean-Louis Bergamo (...) (21 years ago, 9-Dec-03, to lugnet.trains, FTX) !!

Here is another very easy way for your consideration, all you need is the actuator from the 12V points/switch or the 12V automatic level crossings, a short length of string (Lego string is good :-) ) and a dab of glue.
