Ian I am assuming you are using dc current. try reversing the wires to one section just for the heck of it. It should be easy to change back, just change them around on one of the controllers.
A DPDT switch would be used on a short section of track between the two that is completely isolated from both sections but supplied with power just like you would wire a reversing loop.
You do have an insulated joint on both tracks don't you? The small locomotive is possibly able to free roll far enough that it isn't a problem. I have seen it occur that even though the polarity is the same using the reversing switch you need to be sure that the reversing switches on each section are in the same position as the train moves in the same direction. using the same power supply with two different controllers shouldn't be any problem at all. In effect what you are doing is moving between blocks. Something very simple is causing this problem.
