Honetly I don't think trains would ever be popular. We are too conditioned to want to get there as fast as possible. I looked at taking a train from Monaco to Valencia spain it was 19 hours with three transfers. I was like naw we will just fly in an hour and a half. I can see them being more popular in the northeast coridor, but outside of that the distances are much larger than europe. But when train tickets are similar to flights......people are going to fly instead
if trains wouldn't be popular they wouldn't spend millions lobbying against it.
