The way Amtrak is currently set up, there’s no real incentive to undertake incremental improvements. The Northeast Corridor already generates an operating profit, which simply defrays losses elsewhere in the system. Making it run better doesn’t generate any wins for the people who would have to do the work, and would plausibly just lead Congress to reduce subsidies.
…America’s railroads ship a dramatically larger share of total goods than their European peers. And this is no coincidence. Outside of the Northeast Corridor, the railroad infrastructure is generally owned by freight companies — Amtrak is just piggybacking on the spare capacity.
That means the technology isn’t optimized for passenger rail needs. But it also means passenger train scheduling needs to take a back seat to freight priorities.
