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.

Of course the yellow lever must be in the position shown and it does not move
when the points are actuated. If a train comes through ‘against’ the points
it can easily push the movable piece against the weak magnetism of the
actuator.

Hi John,
Thank you for this complement. Do you think the 12V actuator could work with a
9V tension? I don’t have such 12V actuator yet but your suggestions is very
smart and so simple.

Hi Philippe,
yes, mine operate from 9V but the string must have a little slack when it is in
the relaxed position. This gives the mechanism a chance to accumulate some
inertia before it has to do any work.
I think it would work even better if you used ‘SNOB’* techniques so that the
capstan is the same level as the rail thereby allowing a direct path for the
string.
