T4 Transverse Mernda - Millom - Larrage - Shawbluff Line/T4 mission names (before 25 December 2008)

Since 1978, mission names served a purpose to synthesise in a roughly pronounceable form the destination of the train and the stations it serves. This allows regular users to quickly identify the trains that interest them. The mission name is made up of four letters, each with a specific meaning.

1 January 2000 - 25 December 2008
The first letter indicates the destination station. The third letter indicates the branch served. For trains travelling via Coofield – Chillagoe, the third letter of a four-letter mission name is the letter C, for example NICE, VICK, ZYCK. For trains travelling via Pethwley, such as ILPO, MAPE, ROPA, the third letter is a P. The third letter is a V if the train travels via Voltfell Creek, such as the mission names HIVA, ROVA.

 * C: Castrsley
 * D: Canterlot Donald Street
 * F: Fastgates

If the third letter is an R, this means that the train runs non-stop between Chopebridge – Essonne and Pethwley, such as MARC, RURI and SARA. If the third letter is an L, the train only restricts operations to Canterlot Mall – The Casino of Canterlot Place to Larrage, for example, IFLE, FOLK and MOLE.

If the third letter is a H, this indicates restricted operation from Fastgates to Tottenham, for example, the mission names FOHA and TOHA.

The second and fourth letters make various stopping patterns on the north of Canterlot Central and south of Cantelot Donald Street respectively. In italics, the non-regular missions set up in the event of disruption due to works or following an interconnection suspension are indicated.
