A portion of the MBTA Commuter Rail Line was still experiencing delays Friday following a "slow-speed" derailment a day earlier.
The Framingham-Worcester Line was expected to experience delays of up to 20 minutes into the evening commute, according to the agency.
Human error is to blame for the derailment near Landsdowne station in Boston Thursday afternoon, the MBTA said.
Keolis, which operates the Commuter Rail, said an initial report suggests the derailment was the result of an operator’s error in lining a switch.
"There was a derailment I guess and they keep postponing but they haven't told us where we're going to go," commuter Peter Shinas said Friday morning.
As crews continued working on the issue Friday morning, the MBTA alerted commuters through Twitter to allow extra travel time.

"Well now I cannot get to my house and I have been stuck here for over an hour. It sucks," commuter Susana Mendez Kalkachb said in frustration.
That frustration boiled over as the derailment added to a series of other derailments this past summer that caused massive delays and disrupted service for days.
"This is my second time in Boston in four months and my second train derailment in four months," traveler Angie Kinney remarked.
The MBTA provided shuttle buses to help get some passengers to their destinations in order to alleviate the wait times.
"We're going to take the shuttle to wherever they drop us off and hopefully get home," Kinney said.
No passengers were in the train that derailed on Friday and no injuries were reported. The train stayed upright despite the derailment.
It is unclear when the Framingham/Worcester line will return to its normal schedule.
In a separate issue with the Commuter Rail line, Worcester Train 501 from South Station was canceled Friday morning due to a mechanical issue with the main engine, according to the MBTA.
