I noticed the same thing! pretty sure the regular commuter train I use doesn't wobble as much for most of the trip, granted it goes a fair bit slower of course.

I noticed the same thing! pretty sure the regular commuter train I use doesn't wobble as much for most of the trip, granted it goes a fair bit slower of course.
