I am having a problem with the locomotive slowing through one quadrant of what can be considered a basic oval on a 4’ x 8’ sheet of plywood. The track is Lionel O gage not O-27 and I am using two lockon’s. With the train traveling forward in a clockwise direction it will slow dramatically in what could be thought of as the upper left quadrant. It returns to normal when it leaves that quadrant. Again it is the upper left quadrant. The louckon’s are located in the upper right quadrant and the lower left quadrant.
I have felt the track joints for a hot spot after opperating the train but have felt none. I have checked the voltage rail to rail at various spots around the layout – prior to , in and across the slow down quadrant. No voltage drops were noted. My meter does not measure AC amps.
Testing the track with rolling stock by hand does not reveal any tight spots.
I have operated the locomotive using each lockon alone and in combination with the same results.
Here is the kicker with the train traveling forward in a clockwise direction the upper left quadrant is the slow down quadrant. Put the locomotive in revese so it is backing around the layout in a counterclockwise direction and the slowdown quadrant becomes the lower right quadrant.
Any ideas or advice?
Thanks much,
Steve
