..... Yea, "buy new" vs bend the rails back and see how it goes. Don't check the retaining tabs that often come loose. Ignore note any other possible issues with 0-27 too. Don't check anything before you screw it down, you'd have no excuse to pull it up again

I never questioned Bob's advice. The O.P. was on to the possibility of doing it too.
I may be long winded (see "Asperger's Syndrome") but please tell me where I'm incorrect or assumed the O.P. has $30-40 to burn on track, vs a tool that would fix it and be useful in the long run of the hobby.... I gave him a good way to make a better tool, and acknowledged a prefab.
I mention dulling them and do myself, because my brother cut ours a few times over the years trying to tighten the wrap, vs crimping the notch. The rest is about slowing in curves, or is safety related.
There is a 3 inch hole an inch deep on my layout melted away by a hollow pin I missed. It didn't melt the grass mat, just the foam under it. I only found it because it was glowing red hot during a night session. I knew the hollow pins were weak and got hot, but seeing it was a wake-up.
Here's more food for thought to complicate life more.
The track might have been fine, within gauge tolorances.
But the wheels might be slightly out of gauge; in need of a slight press or tap with wood and a hammer.
Measured from flange to flange on 2 drivers any wider than 1-1/8" and that could have been the issue, or compounding it.
