Filing the rail helped. I have to be a little selective of which car I put behind the loco, but most are working fine now. I am still using old style couplers as my set is about 20 years old. Finally getting back into the hobby with my little boy and hadn't started upgrading those parts yet. Just trying to get a layout squared away first. Gets me to thinking maybe I should make the change prior to nailing down the track to a more permanent setup.
Thanks for the inputs
