Yeah, when I used Amtrak I called ahead to be sure they had a box. I figured that I'd get a bike box from a bike shop, a big screen TV box, or something on the way to the train station if I had to, but I never needed to since they have always had the boxes when I needed them. Still best to call ahead. Also be sure there is baggage service anywhere you need to get on or off of the train, unless the train allows you to roll the bike on (some trains do).
