{{Amtrak’s $2 billion effort to replace its fleet of Acela express trains on the Washington-to-Boston corridor has hit a foreseeable snag: The new trains have to run on an old railroad.
The trains from France-based Alstom were originally set to begin service in 2021, but Amtrak and Alstom officials now say they will remain sidetracked at least until 2024 as the manufacturer struggles with mandatory testing intended to show how the units will perform in real-world conditions.
The core problem, they say, is that the Acela runs on tracks shared with commuter and freight trains—not the purpose-built, high-speed tracks found in Europe and Asia.}}
