Question re 6-wheeled trucks/bogies

[RobertInOntario]

Before you start modifying the trucks, make sure you don't have dips or bumps in the track. If you have uneven track, the axles will tend to lift and lever off the tracks on long 3 axle trucks. The shorter 2 axle trucks may be more forgiving, but if the track is uneven you have not fixed the problem by removing axles from the trucks.

Yes, I'm afraid that is probably a large part of the problem. I've a couple other threads on my "layout woes" (see: <!-- l --><a class="postlink-local" href="http://www.the-gauge.net/forum/viewtopic.php?f=46&t=380">viewtopic.php?f=46&t=380</a><!-- l -->). Basically, my main layout has been my "learning curve" project and it has a few bumps and uneven sections (because I've moved and relaid track so often). I've tried to correct these but there are still some remaining.

If I can't adequately fix these problems by June, I might set this layout aside and consider expanding my smaller one which actually works very well.
