A car on a Fitchburg Line train slipped off the rails - but stayed upright - outside the Waverly stop around 7:30 a.m. Riders were given the option of waiting for a relief train - which still hadn't come after an hour - or walking to the nearest station.
Chris R. has been tweeting updates. At 8:50, he reported:
Train did derail and passengers were given the option to walk to next stop or stay on train. Passengers still waiting for relief, been over an hour now.
Bathrooms no longer in service as they are unable to be flushed. Still no updates on relief train.
