When the Riverside extension was opened the first station west of Kenmore was named Fenway, although I don't know whether Kenmore or Fenway is closest to the park.
If you are heading to Fenway Park on the T you get off at Kenmore square on the Greenline (B, C, D trains) if you are coming from inbound headed outbound. If you are coming from outbound headed inbound you can get off at Fenway stop only on the D train, and Kenmore on the B, C, or D branch. The Kenmore square stop is by far the more popular and crowded station for game day traffic and closest to the Park. Don't take the E branch train that runs to Heath street on the Green if you're trying to get to Fenway.
And by God why can't Lionel or MTH make a Boeing LRV or one of the type 7, 8, or the new 9 models from the greenline. These Green Line LRV type cars running as single units or paired have always been way more unique in styling than the more conventional looking long string of cars for other subways (NY, Chicago, Washington etc.) or the ones done on O for NY or Chicago. Even for the MBTA's other lines that are conventional (Red, Blue, Orange) those cars and lines don't compare to the greenline cars for style and uniqueness in their real world appearance, functions, or operation.
I believe these would sell in sufficient quantities to make a profit given the history of the Boston subway as America's oldest and first, the unique design, and the legacy of the Greenline branches and their dual function as subway/street trolley. If you have ridden the Greenline on the T you will understand and know what I'm saying.
I think Charles Ro would sell many by themselves.
