Amtrak plans to furlough 1,950 unionized workers in federal fiscal year 2021, which begins on Oct. 1.
Trains magazine reported that the intercity passenger carrier also plans to end 100 management jobs.
Most of those being furloughed are on-board service employees who will no longer be needed after Amtrak reduces the frequency of most long-distance trains to tri-weekly in October.
Those 698 workers are represented by the Amtrak Service Workers Council.
Other planned furloughs include 509 employees represented by SMART-TD, 390 workers represented by the Brotherhood of Locomotive Engineers and Trainmen, 326 employees represented by the Transportation Communications Union, and 27 employees represented by the American Railway and Airway Supervisors Association.
Those employees are based in Los Angeles (236 workers), Chicago (171 workers) and Seattle (129) among other cities.
Amtrak said the furloughs could increase or decrease by as much as 2 percent once its operating plan is worked out.
The furloughed workers will continue to receive medical benefits paid by Amtrak until they are recalled or through Sept. 30, 2021, if they are not.
Managers who are being laid off are to be notified on Sept. 16.
Earlier this year Amtrak offered voluntary buyouts as part of an effort to reduce its workforce by 20 percent.
It warned at that time that involuntary furloughs would be imposed to make up the difference between the number of involuntary buyouts and the number of workers that the carrier wanted to reach.
