I have been carrying out some experiments on shimming the guard rail slots on Peco turnouts to improve their performance (on another subject thread). I have not yet posted many of my findings yet, but I did start out experimenting with these little compact curved Y turnouts. I was quite surprised to find that a number of my 8 main driver steam engines actually made it thru these turnouts okay,...at least in the forward direction. I have NOT yet shimmed some of their guard rails to see if I can improve upon their performance, but I am rather confident I can,...at least in the forward driving direction.
What concerns me the most would be an analogy with the much larger radius dbl-curved Pecos that had problems with rail cars BACKING thru them. Since the radius of these small Y's is effectively 24” compared with the inner radius of those dbl-curves at 30” , one would well image these short Y's will be very susceptible to derails when cars or engines are backing thru them. Will the shimming of the guard rails solve the problem??

If things work out with the shims, I'm going to need 6 more of these 'little monsters',...as I now refer to them,.....ha..ha
