Rob: Take your vernier calipers and measure the back-to-back on the axles that derail. The minimum you should get is 14mm, 14.5 is better. If it's more than that they need to be squeezed. Also check the distance of the check rails/guard rails that they go through. Peco have changed their flangeway widths over the years.
Spin the wheels to see how much they wobble.
(Lee Valley sells a batch of vernier calipers fairly cheaply. I bought a really crappy one in the $ store for $1 -- it bangs about in the toolbox.)
