Hello. I am needing to get from SC to NE and so far the train is looking to be the best option. Are plastic storage totes which do not exceed the oversized baggage limits allowed? I will purchase more luggage if necessary but would much rather just use my tote with the luggage i already have if possible. Also do checked bags go thru til your last stop or do you pick it up and recheck it at each stop? There are 4+ hour layovers. I have never traveled via train so I am extremely unfamiliar with things any help is greatly appreciated.
