You know, it was always fun talking with you at the events, but I have
got to admit, I really miss those crossing gates that you have. Those
things are AWESOME.

Oh yeah! I remember seeing those at a show before I joined NELUG. I went out
that day and bought some reed switches. The next day I spent a few hours
burning my fingers and melting the things together. I never did get them to
work properly.

The reed switch sensors
are a bit tricky. There’s not much room to work with, so you’ve gotta use
pretty small switches. And they are very easy to break, basically being tiny
glass tubes. (About half of my sensors no longer work.) For some reason, you
need to lay them lengthwise along the track to get the best response from the
train couplings, which doesn’t help the geometry any, either. And don’t make
the mistake of hooking one up to a motor output or you’ll weld the contacts
closed in a real hurry.
I remember at various points offering these sensors to club members at my cost
of materials, but nobody took me up on it. I also gave Joe Comeau a handful of
switches so he could give it a try, but I never heard whether he got them
working, either. Well, maybe it’s time to cook up a fresh batch of sensors.
