Frog rails

Some of the turnouts have got their frog rails in place. Each such rail has to been filed to a sharp point and slid into the styrene frog block. I equip one of the rails in each turnout with a feeder wire, and then solder the two rails together by flooding solder between the rails at the point were they meet. I will connect the other end of the feeder wire to the corresponding Tortoise, and thus get a frog that changes electrical polarity when the turnout is thrown.

Here is a picture of one of the turnouts with the frog rails installed.

And a closer look that clearly shows the gap in the rails that keep the frog electrically isolated from the other rails.

Last, a shot of the cross-over.

Three more frogs to do. The I can start to wire rails and install switch machines, and finallý get the (single) train running.
