MTH Z-750 wireless remote expansion

[Anonymous]

I'm new at this so excuse my ignorance.

I have an MTH Z-750 transformer with wireless remote. Right now the track is a figure-8 but I want to create a loop around that and connect the 2 patterns with (2) switches. Having done that I find that I can only provide power to the outside loop where I have the wireless lock-on. Once the train goes into the figure-8 there is no power. I would think I would have to add another lock-on but I can't figure out how since the one I have is wireless and connects directly into the transformer using a built-in cable. Does anyone have any ideas? Could I use another transformer on the figure-8? Would that hose the other track?

Thanks in advance.
