I am planning a tour in June which involves taking an Amtrak to burlington VT and riding to Montreal, then taking Amtrak from Montreal back to NYC. I own both a Brompton and a BF crusoe but am not sure which to take on this trip. The crusoe rides better but might be a problem due to its large folded size on Amtrak as carry-on, even though the regs state that folding bikes can be taken onboard as long as size is less than 48" x 38" which the folded and bagged BF is well within. I am looking for opinions on this.
