Problem solved with just one reply. Thanks

I was not aware of the policy change. I was in an Amtrak station today and they had 2 lines painted on the wall and a rectangle line painted on the floor with a sign that read, if your Carry on does not fit inside these lines you cannot take it aboard the train. I knew that not many folding bike would fit inside those lines.

Even thought I could do the work myself I know that building a bike would cost far more that buying a factory made bike. Thanks again.
