The MBTA will hold a drill inside the Riverside Line's tunnel between Kenmore and Fenway stations between 8:30 and 10:30 a.m. on Sunday:
The exercise is designed to establish a learning environment for public safety officials to exercise emergency response plans, policies, and procedures as they pertain to a mass casualty event on a Green Line subway train in a tunnel area. To ensure an effective exercise, subject matter experts and representatives from numerous agencies took part in the planning process and will take part in the exercise conduct and evaluation.
As part of the exercise scenario, a train is traveling westbound between Kenmore Station and Fenway Station; suddenly, for unknown reasons, the train derails and makes contact with the tunnel wall. Several passengers are “injured” and others must evacuate the train.
The Green Line out to Riverside was already scheduled to be shut this weekend for repairs.
