This guideline is a short introduction to the naming policy of the model railway track layout svg.

Bell

• the bell itself: bell
• number and square next to the bell: bell0
• sonic beams of the bell: bell_sonic

Error Messages

• each train and wagon has a dedicated error label and number field to show errors
  
  • the label is identified with TRAIN_OR_WAGON_error
  • the number is identified with TRAIN_OR_WAGON_error_number
    
    • a train is identified with trainX
    • a wagon Y of train X is identified with trainX_Y. The front wagon has index 0, the rear wagon has index 1.
  • examples: train1_error, train5_error_number, train1_0_error, train5_1_error_number
• there is one additional error label and number to show collision errors. These are collision_error and collision_error_number

Lamps

• lamp and corresponding number: lampX (e.g. lamp0)
• only the background of the lamps (without the corresponding number): lampX_bg (e.g. lamp0_bg)

Points

• point and corresponding number: pointX (e.g. point0)
• only the background of the points (without the corresponding number): pointX_bg (e.g. point0_bg)

Railroad Crossing

• number and circle: rcX (e.g. rc0)
• closed railroad gates (long): gateX (e.g. gate0)
• open railroad gates (short): ogateX (e.g. ogate0)
  

Signals

• on unidirectional tracks: track name and chosen color (e.g. OC_LN_2Red)
• on bidirectional tracks: track name, direction and chosen color (e.g. KH_ST_1fwdYellow or KH_ST_1revYellow)

Contacts

• contactX followed by its corresponding track name (e.g. contact0KH_ST_3, contact1_KH_ST_3)
• the first contact in (main) travel direction has the index 0, whereas the second contact hat the index 1.

Tracks

• without branches: the corresponding track name (e.g. KH_ST_0)
• with branches: track and branch name merged with branch (e.g. KH_ST_0branchKIO_LN_0)
  

Trains

• the general naming scheme is trainX followed by the wagon _Y. The front wagon has index 0, the rear wagon has index 1.
  
  • front wagons: train0_0, train1_0, etc.
    
  • rear wagon: train0_1, train1_1, etc.

Areas

• pink area: KH_ST_area
• yellow area: IC_ST_area
• green area: OC_ST_area
