I have a hybrid layout of EZ Track (Nickel-Silver) and flex track. I have two Bachmann crossovers that have been in the layout nearly a year. I operate the crossovers manually because it's easier to do so than to go through DCC commands.
Ten days or so ago, I manually changed one crossover from divergent to straight, and the system shorted out. I turned it back to divergent, and the system restarted. That happened several times in a row, so I unplugged the layout, re-plugged it, and everything worked fine. The next day, the same thing occurred, then it went downhill from there. For a short time, I could physically adjust the crossover's position by pressing down on it and keep it from shorting. But that changed, too.
Now, whenever locomotive wheels touch the frog, the system shorts. This problems occurs only when the loco is traveling the main line. If it is on the divergent rail, no short occurs. Flipping the manual switch in either direction does not short the layout.
My guess is that the DCC decoder in the unit has malfunctioned, and it is not properly directing the current through the frog.
In the picture below, you can see the narrowness of the gap between the frog and the junction of the main and divergent rails on the right. I have widened that gap slightly, but doing so did not change the problem.
The other crossover works well. In it, the corresponding gap is slightly larger than one that is giving trouble. With the widening of the gap, they are now about the same.
I've searched this forum and have done Google searches as well. I've consulted two members of this forum, but have not been able to straighten out this problem.
The only solution may be removing the crossover and replacing it with a pair of large radius turnouts.
Any other ideas out there? I welcome any advice that could help me resolve this problem.
Thanks.
