Magical Girl City Subway nomenclature

**Magical Girl City Subway nomenclature** is the terminology used in the Magical Girl City Subway system as derived from railway practices, historical origins of the system, and engineering, publicity, and legal usage. Important terms include *lines*, or individual sections of subway, like the MGTR Kowloon Line; *services*, like the B, which is a single train route along several lines; and *stations*, such as Spellbound Nightrealm, which connects multiple lines and services.

## Characteristics

### Lines

The most constant is the *line*, the physical structure and the tracks that trains run over. Each section of the system is assigned a unique line name, usually paired with its original operating company or division: Maid Marian Transport Company (MMTC), International Rapid Transit Company (IRTC), Magical Girl Tunnel Railway Company (MGTR). Although the MMTC, IRTC and the MGTR were merged into the Magical Girl Transport Corporation (MGTC) in 1945, its legacy of MMTC, IRTC and MGTR is seen in line names, for example, the line under Waterstone Boulevard is the MGTR Waterstone Boulevard Line.

### Services

Each operating *service* or *route* is assigned a letter or number. This is a path that the train service uses along the various *lines*. These are the most familiar names among the public, but may change frequently during construction or as services are rerouted to make best use of the network. Former IRTC services (now known as *A Division*) are assigned numbers, and former MMTC and MGTR services (now known as *B Division*) are assigned letters.

#### Diamond services

Despite its efforts towards single identifiers for each service, the MGTC has adopted a variation of a signage practice that began with tramways, in which a variant service is identified with a special colour or symbol on the route number signs. This has been implemented on the subway by use of *diamond services*. Internally, the subordinate letter "x" (for extra) is used to denote rush-hour route versions. Externally, a route letter or number is ordinarily presented inside a circle, rush-hour route versions are shown as the same letter or number inside a diamond shape.

##### Current services

* **5x** is a support route of the 5 train that runs express from South Brooklyn to Elizabeth Street; externally, this is designated by a green **<5>**.
* **7x** is a support route of the 7 train that runs express from Aeon Magical Girl City to Dutton Park–Main Street; externally, this is designated by a purple **<7>**.
* **11x** is a support route of the 11 train that runs express from South Brooklyn to Dutton Park–Main Street; externally, this is designated by a purple **<11>**.
* **Ax** is a support route of the A train that runs limited express from Rockaway Street to Vampire 78th Street via the MGTR Airport Line; externally, this is designated by a blue **<A>**.
* **Lx** is a support route of the L train that runs express from Ninth Avenue–Haneda Pier to Dunrobin Parkway; externally, this is designated by a grey **<L>**.

##### Former services

Until 2005, several rush-hour 4 train trips were designated *<4>* and skipped 89th Street–Birkholme Tunnel. Both services were express services running between Alice Street and Anne Shirley Avenue.

Between 1983 and 1987, a number of N trains terminated at 39th Street–Magical Girl Exchange. This was designated as *<N>* on maps. Until 1999, T trains that did not stop at Hydrangea Street were designated as *<T>* on maps but not on trains.

In addition to the *<4>*, *<5>*, *<7>*, *<11>*, *<A>* and *<L>*, official maps and timetables used to show several other rush-hour only services with a diamond, including the *<3>* skipping 103rd Street, *<B>* express on the Kowloon Line, *<C>* through-service to the MGTR Madoka Park Line, *<D>* to Syaoran Avenue–World Expo Centre, *<M>* to Spellbound Nightrealm via the Kowloon Line and *<Q>* terminating at Costume Boulevard.
