I just spoke to a service agent at the Lorton Va. Autotrain station and he told me they will in fact take Spyders on the train. They have taken Spyders already. He said the only problem is they have no way to tie down the bike so you will have to sign a waiver for this. I would hope the parking brake would be sufficient. I ride with Amtrak quite a bit and can only see this as adding more fun by combining the two modes of travel. I'm now planning to take my RT-S to Dizzy World in July. I much prefer to bike and train rather than fly! I hope this info helps others out too. The Phone # to Lorton station is:703-690-3615:clap:
