MBTA commuters faced more headaches Thursday, hours after two MBTA Green Line trollies collided and derailed underground near the Government Center T station.
"How do we trust it if there's all these accidents?" commuter Raj Singh asked of the late-night crash.
The T said that 20 to 25 passengers were on one train when it crashed into an empty two-car train that was preparing to enter Government Center on Wednesdya night.
No passengers were hurt, but four trolley operators were taken to Massachusetts General Hospital with injuries. They are expected to be OK.
One train had been been re-railed as of Thursday morning, the MBTA said.
Green Line commuter Richard Costa said, "Oh my God, I've been riding on it for like 50 years ... on the Green Line always, and it's a little scary, honestly."
About half a dozen stops on the Green and Blue Lines were impacted by service delays as maintenance crews worked to re-rail the trains Thursday. Regular service resumed with some delays and shuttle buses that had been put in place were phased out shortly before 2 p.m., the MBTA said.
Because of the crash, commuters were forced to take a shuttle or walk to work on Thursday morning.
"This is nuts because people have to get to work. You have the early morning people, you know, that work in factories, what have you, retail stores, what have you, and a lot of times the supervisor doesn't want to hear their excuse," Singh said.
"Either Uber or get on a plane to get to work so, one of the two, but I guess we'll figure it out," joked one commuter named Justin.
Anneliese Macedo, who was trying to get from Beverly to Brookline and had to take a shuttle Thursday, called it a nightmare
"The driver took the worst … route that he could think of, so everything is behind," she said.
The T is still investigating what caused the collision and derailment.
The crash happened around 9:20 p.m. Wednesday near Government Center and caused a service interruption, initially between Park Street and Somerville's Union Square.
A total of four people were taken to the hospital, according to Boston EMS. Three Green Line operators were taken to Massachusetts General Hospital with unspecified injuries, the MBTA told NBC10 Boston. One of the Green Line operators was discharged from MGH, a spokesperson said Thursday morning. Both of the trains were derailed in the collision.
More on the MBTA
The Green Line crash adds to a long list of incidents that have happened on the tracks of the MBTA.
Just three months ago, the agency committed $25 million to speed up the installation of anti-collision technology on the Green Line.
The investment came after two trolleys on the B Branch of the Green Line collided on Commonwealth Avenue, injuring 27 people aboard, including four train operators. A subsequent NTSB investigation found one train was going triple the speed limit. The trolley operator, Owen Turner, was charged with negligence last fall.

In January, former Suffolk County District Attorney Rachel Rollins launched a criminal probe into MBTA safety issues in response to the trolley crash.
The T also faced other safety incidents in September of last year. A Red Line train with nearly 50 people on board derailed and hit platform at the Broadway Station. Also in that same month, nine people were hurt after an escalator malfunction at the Back Bay Station.
More recently, Robinson Lalin, 39, of Dorchester, died after getting his arm stuck because of a door malfunction on the Red Line.
