Here's another update on B division subway car assignments - which is on another thread:
The R-44's are ALL retired except for the 63 on SIR as of last Saturday.
All 240 R-32's still in service are assigned to 207th Street for service on the C, and occasional service on the A.
All 50 R-42's still in service are based in East NY and running on the J/Z.
The R-46's are divided between Jamaica and Pitkin, running on the A, F, G, and R.
The R-68's are divided between Concourse and Coney, running on the B,D,N, and Franklin Avenue Shuttle.
The R-143's are exclusively on the L.
The R-160's, the new workhorse of the system, are divided among Jamaica, Coney, and East NY. They're running on the E, F, J, Z, L, M, N, Q, and R.
As to the propositin that the R-32's were well made - I agree, although I regret that none were kept in their original condition with fans. My other favorite model was the R-10's.
