In most cases, this was accomplished by simply eliminating the second letter in route designations. There is no longer a letter designation for specials (formerly "S"). By the 1990s, the TA were moving steadily toward using traditional line names on maps and especially on signage. All of the southern Brooklyn subway lines now show the traditional line names (except for the BMT Fourth Avenue Line) in order to distinguish between services going to Coney Island via different lines. On BMT/IND equipment branch line names frequently appear on operating trains, in addition to the route letter. R32 equipment with rollsigns, for example, may read:  Newer rollsigns on R40 up to the R68A (including the former rollsigns on the R44 and R46 that now have LCD displays) have the route's bullet on the left side, and the two destinations on the right side. A rollsign on an R68 "" train may read:  One change which precedes pre-unification has to do with the use of locality names. While these were discouraged during the 1960s after they had been inherited from private operators, many terminal stations are once again described by both a community and a street name; e.g., "Inwood"–207th Street for the northern destination of the "A" service, and "Wakefield"–241st Street for the northern destination of the "2" service. The JFK Express, started in 1978 and discontinued in 1990, used a turquoise bullet; this stayed through the color change. Since the unsuccessful attempts at applying the briefly popular schematic theory of diagrammatic maps, line-by-line color-coding, and exclusive use of numbers and letters for service and line descriptions, the MTA has moved steadily toward a more traditional approach, with more geographically correct maps and use of traditional line and community names on maps and public signage. Concurrently, it has been refining its use of the number and letter system to try to achieve consistency across the system. One major push has been an attempt to have as many services as possible serve the same stations, routes and terminals at all times, with the major exception for most services being the early morning hours of approximately midnight to 5 a.m. For instance, the "B" and "C" swapped northern terminals in 1998 so the "C" could serve the entire local portion of the IND Eighth Avenue Line at all times except nights; previously, the "A" had made two local stops north of 145th Street on weekends, while being express on the whole line south of 145th Street, because the "B" did not operate in Manhattan on weekends.
