Need help repairing broken truck gears

Here's the catch22.

If you make one truck one axle drive by removing the broken gear, if that truck is the one with the motor and the tachometer- then it has less traction and will go into wheel slip easier. the kicker again, is if that is the tachometer motor going into wheel slip, it then determines the power for the second motor- in theory now one with both axles driven and less likely to slip.

In other words, you would stall out and be prone to stalling out.

If you do what you are proposing, you need the stronger traction truck (all wheels driven) on the motor with the tach to prevent this stalled out slipping situation where the tachometer is not seeing the true load of the engine.

Thanks. For some reason my searches of “powered truck” and subway truck brought nothing.  

Try searching for 4-WHEEL TRUCK / POWERED and I think you'll find a lot of entries.  Use the exact spacing of the red text.

Yeah seems spacing and dashes make a huge difference

I have had this happen with the Lionel subway trains as well. I chalk it up to lack of lubrication sometimes. In the Lionel subway train issue I just replaced the trucks at Lionel. They are $25 apiece. If they are available from MTH, it would be much easier just to swap them out.
