Did she perfect time travel? That's the only way rail will replace air travel over long distances. I went to Chicago when I hit 50, because my cousin, her mom & husband were there to see her son and I took the train partially because I didn't want to deal with traffic and parking. Round trip cost about $40 from Milwaukee and I couldn't do it for less if I drove or flew ,even considering taxi fares. Cross country, I would only do rail if I had a lot of time for the trip and in order to build a high speed rail system, it would be difficult, considering everything that as already been built. If we were starting from scratch, I would absolutely want high speed but the operational costs still need to be considered- it may be faster, but if it's more expensive to operate, it's going to lose customers.
MKE has a new trolley system that was installed because the Mayor has a big stiffy about it- it's never going to succeed and even before it was finished, he started talking about expansion. One of the first things that happened when they started digging to lay the track- they found old tracks that were covered in the '60s, when they abandoned the last trolley system. This is Wisconsin and they went from rails to rubber tires in the '50s when they had problems with traffic, ice buildup, etc. Then, a crane took out some power wires, the rails waiting to be installed occupied traffic lanes that were needed, people on bikes and motorcycles got their tires stuck in the rails, and the cost seemed too high to make it work, so the local casino fired up for as year worth of free passes. Now, they're talking about higher than expected ridership- I don't know what they expected, IT'S FREE! Of course they'll have more riders!
