Wiring Tortoise Switch Machines to Atlas Code 55 Turnouts
Posted by CP Railfan on Sunday, February 4, 2007 3:40 PM
I am looking for information from anyone who is familiar with wiring Tortoise Switch Machines to Atlas Code 55 n-scale turnouts. On the back of the packages the turnouts come in, Atlas shows a wiring diagram for wiring their switch relay to the terminal near the frog. I would like to know if anyone knows what terminal on the Tortoise Switch Machine connects to that terminal?

I do not have an Atlas Code 55 turnout package to look at, but I assume that this is to power the hot frog.??   If this is true, then it can be done with two different sets of contacts from the tortoise.

1. connect track power to pins 2 and 3.  Connect the frog to pin 4.

2. connect track power to pins 6 and 7.  Connect the frog to pin 5.

In either case the track power "polarity" would need to be flipped one way or the other to  make the frog power match the direction of the points. 

There should be a wiring diagram that came with the tortoise machine. This information is in figure 2 of that document.

I have been trying to find this out myself.

There IS no wiring diagram for frog power in the Tortoise manual sheet, otherwise this question would never have been posed. The only wiring diagram is for the basic switch function.  The manual sheet only refers to a separate sheet from Circuitron regarding the wiring of the other terminals which is only obtained from writing to them (apparently Circuitron is still stuck in the 20th century...)

Your info above is correct, but not complete. How can one wire the terminals and avoid a short circuit?  As I understand 2, 3 and 4 are separate from 5, 6 and 7. One can use either set, but not both for wiring the frog.

I came across a great and simple to read diagram that shows how to wire a Tortoise in a way that will power the frog...

i didn't create it and don't know who did, but I'm using it and it works great...

Why resurrect a 6 1/2 year old thread instead of starting a new one, particularly when your reply does not related to the OP's question?

This is the diagram:

You can see two single-pole, double throw toggles here, terminals 2-3-4 and 5-6-7.  Note that the center posts are 4 and 5, not the "middle" posts in each set.

It takes an iron man to play with a toy iron horse.
