Members - During 2007 Dick Karnes provided a two-part article on this subject
in 1:64 Modeling Guide. I applied Dick's technique to Old Pullman turnouts on
each of two S-Mod standard modules I built, using Bullfrog Manual Turnout
Controls which provide a SPDT to power route the frog.
These turnouts only access an industrial siding on each module. But I've
bolted the modules end-to-end, and want to add a "wing" to each end of the
pair, to create a switching layout on the back wall of our garage. That will
change the two-track mainline on the modules into a passing siding (in order to
run-around and serve additional industries on each wing).
As an aside, I recently replaced the Bullfrog on one module (which had failed
electrically, probably by reason of rough handling of the module) with a
Caboose Industries ground throw Item 220S, which also has a SPDT and was
recommended in Dick's article.
Also from Dick's article, "if one or both tracks are part of your main line or
a passing siding, .... you must gap the rails beyond the frog and provide
jumper wires to power them. .... The solution is to employ
two extra sets of SPST contacts on your turnout throw mechanism."
Here's the question: What manual turnout throw mechanism provides two extra
sets of SPST contacts?
Yes, Bullfrog provides a position for a second SPDT; but has anyone re-worked
that into two sets of SPST contacts?
No, Caboose Industries 220S does not appear to be expandable to add two sets of
SPST contacts.
I believe Tortoise and other electronic turnout machines have this capacity,
however I'd like to stay in a manual environment for both the modules and their
"wings". What solution can you share?
Thanks.
