(CNN) — [Updated at 4:38 p.m. ET Friday]
Amtrak says it has fully restored rail service after it canceled some trains fearing the effects of a looming freight rail worker strike that was averted.
"Amtrak has fully restored service, and all trains will depart from their origins today [Friday]," said the railroad in a statement.
"Some customers at intermediate stations may still be impacted. Customers should check train status on Amtrak.com or the Amtrak app for more information about their trip."
Amtrak canceled all long-distance trains in all corners of the country as well as some state-sponsored routes.

With a tentative deal reached to prevent a freight railroad strike, Amtrak is working to get its schedule back in order.
"Amtrak is working to quickly restore canceled trains and reaching out to impacted customers to accommodate on first available departures," Amtrak said in a statement Thursday morning.
The deal between railroad unions and management was announced just after 5 a.m. ET Thursday in a statement from the White House.
While negotiations did not involve Amtrak or the Amtrak workforce, passenger rail service was adjusted on routes that could have been affected by the dispute.
By Wednesday, Amtrak had announced the suspension of all long-distance Amtrak trains starting Thursday. And later Wednesday evening, Amtrak added that some state-supported trains -- such as those in Virginia -- would not run starting on Thursday evening.
More details are expected soon on whether the dispute's resolution will alter those cancellations.
Here's what Amtrak passengers need to know about the situation:
Is Amtrak striking?
No. "The negotiations do not involve Amtrak or the Amtrak workforce," Amtrak said in a statement earlier this week.
So why is Amtrak canceling service?
Amtrak is preemptively suspending some service because its track will be affected if freight rail workers go on strike.
"Amtrak operates almost all of our 21,000 route miles outside the Northeast Corridor (NEC) on track owned, maintained, and dispatched by freight railroads," said Marc Magliari, an Amtrak spokesman.
The passenger rail carrier said it would only operate trains this week that it "can ensure will have enough time to reach their final destinations by 12:01 a.m. on Friday, Sept. 16."
Will Acela service be affected?
No. Amtrak said most travel within the Northeast corridor (Boston, New York and Washington) would not be affected and Acela would operate a full schedule. Related branch lines to Albany, New York; Harrisburg, Pennsylvania; and Springfield, Massachusetts, also would not be affected.
Amtrak expects minimal changes to Northeast Regional services.
Which routes are affected?
Amtrak announced that all long-distance trains would be canceled starting Thursday. Some routes were suspended earlier in the week.
Some state-supported trains were added to the cancellations starting Thursday evening. The state routes include: Capitol Corridor, Amtrak Cascades, Heartland Flyer, Illinois Service, Michigan Service, Pacific Surfliner (partial), Piedmont, San Joaquins, Springfield Service (north of Springfield) and Virginia Service.
Here's a breakdown on suspended long-distance services:
Suspended services starting Tuesday, September 13:

Amtrak said it would try to contact passengers whose trains are canceled at least 24 hours in advance.
Can I change my ticket?
Yes. Amtrak says it will contact customers who are or may be impacted with offers to change their travel dates. Fare differences will be waived for departures through October 31.
Can I get a refund?
Yes. Impacted customers contacted by Amtrak may receive a full refund without cancellation fees.
Will commuter rail service be affected?
Yes, rail service not provided by Amtrak could be affected by a freight rail strike. Many passenger rail services operate on tracks owned by freight railroads, including Metra in Chicago and Maryland Transit Administration's MARC trains. More on that here.
