The New York City Subway "A" and "C" lines are part of the Eighth Avenue IND Division of subway lines that run express and local, respectively, from Inwood - 207 Street and 168 St in Manhattan to Euclid Av in Brooklyn and Lefferts Blvd, Far Rockaway, and Rockaway Park in Queens. The A Line begins as a local service at 207 St, just south of the Harlem River, which separates the Manhattan island from the Bronx. It runs local until reaching 168 St, where interchange is available with the 1 Line and the "C" local line begins. After only one express stop at 145 St (where the "B" and "D" lines join), the "A" arrives at 125 St, its last stop in uptown Manhattan. It then runs super express, skipping numerous stops and achieving very high speeds, until arriving at the downtown populous of 59 St - Columbus Circle. After passing through Times Square, Penn Station, and Washington Square, the A and C end up at Fulton St (formerly known as Broadway-Nassau with connections to the larger Fulton Street subway complex), where interchange is available with many other lines. It is also the final station in Manhattan. After crossing the East River into busy western Brooklyn, the A and C still retain their express/local relationship. The last stop of particular note in Brooklyn (aside from Euclid Av) is Broadway Junction, where interchange is available with the J, L, Z, and M Shuttle. After arriving at Euclid Av, the C terminates and the A continues as a local service through Grant Avenue station before entering Queens. It now runs overground for the first time with several stops over Liberty Avenue. The A now arrives at Rockaway Blvd after said stops. A massive interlocking guards the rails east of Rockaway Blvd. One set of tracks continues east to Lefferts Blvd with two intermediate stops. The other veers south-easterly, heading through swampy, barren land. It then heads into Broad Channel, which is a peculiar island formation in the middle of the Rockaways and the rest of Queens. A Shuttle train also begins here. It splits just after heading on the Rockaways, with one line heading east to Far Rockaway, where there is a transfer for the Far Rockaway Branch of the LIRR. The other line heads west to Rockaway Park with the Shuttle train. The "A" Line usually utilizes the R46 rolling stock, however it is sometimes seen with R32 rolling stock. The "C" Line usually utilizes the R160 rolling stock, however it is also sometimes seen with R32 rolling stock. This would allow so much of an integration of NYC into TSW/TS20xx and it would revolutionize the current standard of mainline routes/stock.
