Amtrak was set for another record-setting year before the coronavirus crisis hit in early March.

Amtrak is reducing up to 20 percent of its staff, the company said, as the coronavirus crisis wreaks havoc on the passenger railroad service and substantially cuts into its revenue.

The reductions will amount to 3,700 jobs. In an email to the company’s 18,500 workers, chief executive William J. Flynn announced the “essential adjustments” will be completed by October, saying the company will offer “incentives for separations and retirements before we resort to involuntary separations.”
