Bad Wheels Kick Up Dust on the Mainline!

[@robertpeters9438]

Why did the engine rock side to side much more than the cars?

[@thomasboese3793]

A muddy spot with stick rail. Jointed rail is always weakest at the joints, and the locomotives weigh more than the other equipment.

[@IronWheelProductions]

Locomotives usually have more suspension than normal railcars.

[@thomasboese3793]

@@IronWheelProductions No, all rail equipment has suspension 'tuned' for the weight involved, so each point of contact carries the same amount of weight of the item.
The jointed rail, (with or without muddy spots) is a weak spot where the weight will try to force the rail down. Look at any photo of jointed rail and note that the joints are almost always lower than the rest of the track.
FUN FACT: Prototype railroads 'never' have the joints SIDE-BY-SIDE. (Yes, snap-track is used for repairs after a major derailment, which is replaced ASAP.) Model railroads, even with flex-track, have the joints side-by-side, and look at the problems we modelers have if the track is not perfect.

how did the wheels kick up dirt?

[@IronWheelProductions]

@@trivialinsignific The wheels had really bad flat spots which created violent pounding on the tracks. To add on to all of that, I shot the video during a pretty dry time of the year, so there was a lot of loose soil.
