=== Stations === 
Different types of stations allow for single-direction, bi-direction, or express stopping patterns.

* '''Single track''' stations have only one platform and are useful for single-directional loop or a terminus station.
* '''Parallel track''' stations have two platforms and are the typical station used if there are no special requirements.
* '''Quad track''' stations have four platforms and, unlike the other stations are not speed limited to 47Km/h. They are designed to allow an express stopping pattern where local services stop and long-distance services continue through the station at full speed without stopping.

Note that the cost of a '''Quad track''' station is more that the cost of a '''Parallel track''' station with two single track lines built on either side of the two platforms. Careful engineering can therefore save around 27% of the construction cost of each station on a quadruplicated line.
