Hey all,
While at the NMRA show this past July I was talking with a few people
about the custom switches I make and I was given a challenge. In short the
challenge was to make these:
|
The double-Y will be difficult to do with both switches at the same
position. You’d have to have some way to ensure both aren’t set to reverse
(curved) at the same time, and a reliable way to direct the train when both
are normal (straight). Probably better to offset them by a few studs, as
most (all?) such points are normally done.

you make a good point. i should be able to use a 4 or 8 stud offset with
little or no huge problems. either way i think it’s going to be fun which is
what matters anyway. ondrew

Ondrew, I see you have a single slip at 45 degrees there.
I remember seeing a 22.5 degree crossing someone made from 2 straights, so that
if two tracks were 32 studs apart with a switch on each and a straight
connecting them, another track could come down the middle.
One thing I’d really like to see is a single or double slip version of that 22.5
degree crossing. Your stubbie switch “A” looks a good place to start, but you’d
have to cut back to the length of one straight and one curve on the two
branches.
If you have a pair of switches you have the two mechanisms already. The tricky
bit would be the crossing of rails.
This might be easier than the triple point challenge, due to the overlap of
electrical mechanisms.
