What are Amtrak's most profitable routes? It probably makes the most sense to update them first. The Northeast Corridor is clearly the most profitable, thanks to the high population density in that region. The Wolverine route connecting Detroit to Chicago seems quite popular too. Most of the times that I have taken it, the conductor announced that it was sold out. It's likely the second or third most profitable route, which is probably why Amtrak upgraded it to "higher-speed" rail (reaching 110 mph) over the past few years. But delays are still frequent and the trains are aging, so a further update would be welcome.
