My son was given a used E-Z Track "Mountaineer" set, which came with the Spectrum Magnum power pack.  The set-up also includes two turn-out controllers.  I've made the cable connections the way I think they're supposed to be, and the controllers work, but the train does not run.  Please, if anyone can tell me what I've done wrong, I'd appreciate it.  Here's how it's wired up now:  one red cable from the "Variable DC" points on the power pack to the track; the other red cable from the "Accessories AC" points on the power pack to the turnout controller switches.  The turnout controllers operate correctly, and when the speed dial is turned up, the lights in the train engine gradually brighten, but it does not move.  Any help would be appreciated.
