Do not forget spike protection on the track side of the transformer.

If you use the older post war transformers with newer engines then you must have some kind of protection like a TVS (transient voltage suppressor)unit rated around 32 volts and must be bi-directional.

Thanks. I see how to wire a tvs in with a traditional lockon, but how do you wire one in for fastrack?

You could add a crimp on connector to each end of the TVS to allow attachment to the underside tabs of the fastrack - the same connectors used for your terminal wires.

Those exact connectors (.110 crimp connector) are available on Ebay in packages of 100 or so as that size isn't usually available at RadioShack or regular hardware stores.
