When you look at the "not to scale" map of the MBTA network, you might think that the B and C and D lines are actually really far apart from each other. Except that out here, Reservoir station, Cleveland Circle Station and Chestnut Hill Avenue Station are within about five blocks of each other. An easy walk and maybe if you're riding the Green Line into the city, you'll have a quicker ride from Reservoir since there aren't as many stops between here and Kenmore.
Reservoir is on the D branch of the Green Line. A solid above ground station, it has good cover to protect you from the elements, plenty of waiting area, audible and visual announcements of the next trains in both directions, and automated ticketing machines for purchasing a Charlie Ticket or adding value to your Charlie Card.
The station is between Chestnut Hill (about a mile away, outbound) and Beaconsfield inbound. There are a number of bus connections upstairs. read more
