A Boston Green Line trolley with more than 200 riders derailed Friday morning and continues to affect MBTA service.
Around 9 a.m. near Park Station the westbound trolley derailed, forcing rush-hour commuters to walk down the tracks after service was suspended due to the incident, WCVB reported.
Service has been temporarily suspended between Haymarket and Park Street, resulting in severe Green Line delays, according toFox25. Work has begun to re-rail the trolley and resume normal service.
The MBTA has recommended that passengers take the Orange Line to travel between Haymarket and Downtown Crossing, Fox25 added.
Customers wanting to arrive at Government Center should transfer to Blue Line trains at State Street, according to WCVB.
The MBTA, though, expected that the morning derailment would not affect the afternoon commute,Boston.comreported.
"We expect to have the car re-railed long before the late afternoon/early evening commute home," MBTA spokesman Joe Pesaturo wrote in an email quoted by Boston.com.
What caused the derailment remains under investigation, according to WCVB.
