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.
