Turnout derails

All, I am having issues with derails on my inner loop of my layout as I enter a turn just past a turnout. Best guess is that as the engine is entering the turn, it is putting pressure on the truck of the first car behind it to the outside of the turn. This tends to be right where the groove is for the sliding track of the turnout forcing the truck to jump off. It appears to only be the first car behind the engine (which has couples fixed to the chassis vs the truck). A drawing of my layout should be included with derailment locations circled in red. Thoughs were to file down the turnout (Atlas #4 at top and #6 at bottom) so the end of the groove isn't as much of a jump. Anyone else had this issue?

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
I still have some cars that use the old hookhorn couplers. they do not couse any more derailments than the ones that have been converted to Kaydee couplers.
