As we mentioned earlier, 18 of the 20 subway lines are undergoing weekend service changes. Why? Because NYC Transit is performing work on the lines that can't be done during harsher weather. We've got the laundry of service changes after the jump, but the topline is:Riders on the 5, A, F, G, L and E get the shuttle-bus transfer at various points along their routes; the 1, 2, 7, B, N, J and R will skip a section of stops; the 4, 6 and Q lines will run express at times, bypassing more stops; and the D will run on the N during midday hours tomorrow, skipping 12 Brooklyn stops. The lines that aren't getting the service treatment? The M, the Times Square shuttle and the Franklin Avenue shuttle.
