Mine Train v Big Thunder

[Mome Rath]

As others have said, BTMR is louder, jerkier, and shakier (lol) than SDMT. If you really wanted to do a step up as a trial run, try Slinky Dog, IMO, it falls between SDMT and BTMR. Otherwise, if SDMT is fun and you've caught the coaster bug, BTMR is a great second step.
