So I have a Bachmann gandy dancer pump car and trailer that I have converted to battery operation. It runs very well with the exception of sprung points at turnouts. I have four turnouts that are held in place with a light spring. When normal rolling stock passes through these turnouts, all goes according to Hoyle. However the Bachmann pump car is too light to move the points and instead the points cause the pumper to derail. I experimented with adding weight to no avail. So I would like to run it on my tram line that is point to point.
So here's my question. Again, if the pump car was heavier I would install a DPDT toggle switch that would hit a trip at each end of the point to point line and reverse the unit. Since the light weight is an issue, I wonder if there might be some sort of electronic switch that would accomplish what I am after.
Here is a short clip of the unit in question.
