What you have accomplished is very creditable--Nice work!

My experience is that you can have almost as much time in the bending rails--getting them to line up, and stay there*--so don't get discouraged at that point. And don't forget guard rails at the frog.

Woodie--what is your experience regarding this?

*You can CHEAT, and use flex track of course

Looks good Charles. Alignment of the "moving stock rails" is critical. However, I "discovered" that Caboose Industries HO sprung groundthrows offer the critical amount of movement. It may be a bit of fiddling but they work well. Electrical hookup is easy, I will try to draw up a sketch of how I have done this on my old On20 Mogollon Railway which used knob & rod operation in conjunction with a DPDT switch to handle polarity. Sounds trickier than it realy is.

OK, here is a badly rendered diagram:




I didn't use the Caboose groundthrows for this, I needed the frog's polarity switched when the moving rails were aligned. The moving rails were soldered to a piece of PC board for the bridle, copper cut between for insulation. The .015 music wire was the actuator and it ran through some brass/aluminum tube under the layout which had a "kink" in it to maintain the tension. The wire went through the toggle of a small (Radio Shack) DPDT slide switch which had the correct amount of movement, this was epoxied in place in the toggle so it switched the polarity when the rails were thrown. The DPDT was wired as shown. The wire then went through another bit of tubing and then out the side of the layout and a wooden knob was glued on. You can see the wire, tubing, & knob deal in the Gila Tram thread in the Micro layout forum. I hope this helps.

Woodie

*** It could be a SPDT switch also, to save electrons ***

Hi Charles
Way back in one of my posts I added images of a slide switch to throw the turnout and provide frog power to my M/E turnouts on my Lost Creek RR similar but different to Woodie. The switches work very well.
Might offer some other ideas.
Well done on the stub switch.
Rod.
