i think i may have solved my derailment problem? it may have been a q. c. problem with the crossover,the one rail on the point was rolling in towards the center of the track when the loco. was going into it,this rail is very loose compared to all the others,i wasn't sure if i could put a spot of glue on it to stiffen it up,so i turned it around and i have not had a derailment for over a week also no problems in reverse. maybe a bandaid? i also loosened up all the trucks on the cars that came with the set to match other cars i purchased separately train runs smoother now not as jerky it seems. i thought it may have been the loco but it was going on with the three that i have. thanks much for all the help
