Need Extra Weight for Passenger Cars?

[RedMt Dave]

I finally have all of my E-Z track purchased and I am testing my layout with my rail cars. Part of my layout includes a Bachmann 44137 HO E-Z Command DCC #6 Single Crossover Turnout Left and a Bachmann 44138 HO E-Z Command DCC #6 Single Crossover Turnout Right. I thought that I might have trouble with my passenger cars going through the switchover angles. So far so good. However I am having an issue with the passenger rail cars derailing while going straight through this piece of track. I am testing them at a very slow speed. If I manually test each car by itself I can see where the wheels slide as they encounter the switch rail. If I push down slightly on the passenger car it seems to pass the switch rail with no issues. This happens on both left and right crossover turnouts. I do not have the problem with my Bachmann freight cars and they seem to have some weight to them as compared to the longer passenger cars. It would seem that if I could add a little weight over the passenger car wheels, it may solve this issue. Has anyone tried this before?

Reading through some old posts it looks like this is a continuous problem. Some people add weights and some people have modified their turnouts by adding a stiffer wire to the turnout. Any other recommendations are appreciated.

The trucks on the cars may be attached a hair too tightly and unable to slightly rock vertically.  Try loosening the screw the barest minimum, maybe 1/16 of a turn and then 1/8 turn if that doesn't work.  Any more than that and truck tightness isn't the problem.

If the trucks can't slightly play vertically, they can begin nitpicking at everything that cars with properly adjusted trucks won't feel at all.  On real railroads, springs take care of that issue, but our little cars are too light for springs on trucks to have any real function, even though model railroad trucks in the Jurassic often had springs.
