Nano

The Nano description level identifies what happens inside a switch or crossing. It is where the distinction may be made between different types of switches.
Typically, this level will be built starting from the micro level, by using “switch templates”.

Examples:

• 

  Single switch example

• 

  Double switch example

• 

  Nano level example: inside of a switch

Micro

This level defines the network in the nearest way to the physical level as commonly viewed.
Its nonlinear elements are the switch points, the network borders, maybe some administrative points (ownership boundaries), buffer stops, while its linear elements are the tracks connecting those NonLinear Elements. The linear elements will be called ‘track edges’.

Examples:

• 

  Micro level example

• 

  Micro level example: switch

Meso

The Meso level brings the description of the tracks between the operational points of the network into focus.
Its NonLinear Elements are the operational points (OP; e.g. stations, yards, boundaries) and its linear elements are the tracks connecting those elements, which will be called SectionOfTracks.

Examples:

• 

  Meso level example

Macro

The Macro level aims to describe the network at regional or national level, with the NonLinear elements being the boundaries and the major OP’s while the linear elements are the section of lines connecting those points.

Examples:

• 

  Macro level example

• 

  Macro level example: station
