Fast Tracks

Hello out there:
On my old layout I used twin coil switch machines to power all of my shinohara code 70 turnouts. I had little if any problems with breaking the point rail connections. Now that I'm going to be using turnouts using fast track products, and intend to use solid switch points, will the quick movement of the twin coils eventually break the solder joint between the throw bar and the point rails? Thanks. Bill H.
