Better to pair each GLX line with two western branches and allow cross-traffic to change trains anywhere between Lechmere and Kenmore as necessary. Lower-frequency C and D trains could terminate at Union, and the busier B and E trains could be paired with the busier Tufts spur.
As I stated in another thread, GLX will make Brattle Loop useful again since it is the only place to turn a train from the north. Brattle loop is also the tightest due to the sharp curve installed to mate it to the new NB subway in 1963. Stub end terminals such as North Station slow throughput, loops speed things up.
B should stay at Park or Govt. C should run through to Union. D should turn at North Station, E at Park St. G service (West Somerville) should turn at Brattle.
The Broadway Portal was used to turn trips from Clarendon Hill before Lechmere opened, with cars on the surface via Tremont, Berkley, Boylston and Arlington. Lechmere's purpose was to get those cars out of the Subway.
1947 Subway Routes:
9 City Point - North Station (1)
39 Arborway - Park St. (2)
43 Egleston - North Station (1)

The next stop is Washington. Change for Forest Hills Trains on the Winter St. Platform, and Everett Trains on the Summer St. Platform. This is an Ashmont train, change for Braintree at Columbia.
