Headcode is a very important aspect in the train operation in Stepford County Railway. A headcode is composed of four digits, three of them numerical and one alphabetical. The purpose of headcodes are to identify each train with a code and using them to smooth out communications between the drivers and the Dispatchers and Signallers.
The first digit indicates what type of service the train is operating.
- 1 - Express Service (AirLink Nonstop services)
- 2 - Stopping Service (All WaterLine and local Stepford Connect services)
- 5 - Empty Coach Stock (Not in service - While the train moves from the depot to the nearest station)
- 9 - Semi-Fast Service (Stepford Connect and AirLink services that skip some stations)
The second digit is alphabetical and indicates the train's destination.
- A - Stepford Airport Central
- B - Benton
- C - Connolly
- E - Edgemead
- G - Greenslade
- H - Newry Harbour
- J - James Street
- L - Leighton Stepford Road
- M - Morganstown
- N - Newry
- P - Port Benton
- S - Stepford Central
- T - St. Helen's Bridge
- U - Stepford United Football Club
- V - Stepford Victoria
- W - Whitefield
- X - Airport Terminal 2
- Y - Berrily
- Z - Airport Terminal 3
The last two digits are randomly generated. However, a headcode will not overlap with another one in service.
