Happened around 8 a.m. on an inbound Rockport train, according to Bill Kyrouz and Lisse, who were on the train.
Lisse reports the woman tried boarding the train as it was pulling out of the station. Fortunately, she says, a "quick thinking conductor" applied the emergency brake and the woman appeared to suffer only a cut head.
The woman was transported to Beverly Hospital alert and conscious.
Train service on the line is now halted.
