There's actually a pretty solid argument to be made that the railways were never more effective than during the days of Rockefeller, when he could throw his money around to force otherwise-competing railways to optimize their work in an industry that has some fundamental strong incentives to be non-competitive (it rarely makes any sense to run two rail lines purely for competition reasons and leads to a race to the bottom on pricing).
... but that's more a story of the failure of the US government to go far enough and nationalize the rail network and its operations. The most efficient era of US rail was during World War II, when the military took it over and prioritized schedules by optimal throughput over profit concerns.
