Amtrak Engines No Longer Go “Choo Choo!” Now: “Shhhhhhh.”

Amtrak is testing new locomotives to replace the 30-year-old engines that have been hauling passengers up and down the East Coast since Ronald Reagan was president. And these engines have an unexpected advantage over their predecessors: They’re relatively quiet.

Each of the 70 new locomotives costs just over $6.5 million, and Federal Railroad Administrator Joseph Szabo — a former train engineer — was wowed by it.

“It’s just so quiet, so smooth, and quickly accelerates,” Szabo said. “It’s really a thing of beauty. When you board this locomotive, it’s more like going into an office and sitting at a desk with a computer in front of you. It’s really a high-tech environment.”

The first locomotives go into service this fall, CBS Philly reports.
