Traction tire 036 switch problem

Watch this video this for 072 fastrack switch but yours maybe the sameway.

I have seen everything from derailments to track shorts with missing traction tires, you need to replace both traction tires on the truck. What is your engine item number, need the item number to determine which traction tires you need unless you have a micrometer .take a micrometer and measure the wheel grove, for example "22 mm", you can then  purchase the tires from MTH  or Lionel and replace them. Then your train will work perfectly.

here is a picture of a micrometer?

I have seen too much narrow gauging on the wheels. They are pressed too close together and the flange will pick the point.

The micrometer will tell the story.

Sandjam's fix is worth trying, but I spread the wheels to the same width as a car or tender with a tighter flange to rail.

Some slack is needed to accommodate smaller radius curves, but some wheel sets are just too close.

I dealt with pilot trucks, so the driver wheels would be a royal pain. So, tighten up the points like Sandjam's video.

Thanks gentlemen.  The points are pretty flush with outer rail, in fact, the outer rail has a little depression that the tip fits into, so I am not sure that bending the points will be the solution.  How do I say this, it is as if the tire is too thick, rides on the rail too high, and the wheel flange just doesn't catch the point As the rubber just rides over it.  I will check the spacing (Harbor Freight, here I come) but not sure what the next step would be.

David, 

   I run my Legacy Shay with no traction tires what so ever and it runs like a dream,

if your engine preforms correctly, don't worry about using the traction tires.
