  The following lists major steps in developing an own BAHN network layout, in an order that allows for efficient and effective construction, in the opinion of the author of these lines. Details of how each step should be implemented can be found in the extensive BAHN help file, as well as elsewhere in the Internet (these help facilities are not yet available in the Russian language, and a more detailed instruction on layout modelling has been provided in Russian). © Text by Aleks Zabreyko, 2001.

  What is required for a quality BAHN layout

  • Detailed (preferably) track map, except tracks in depots, which are not required
  • Detailed enough list of the rolling stock: type of the vehicles, quantities of each type, and liveries
  • The list of routes and the lines they follow while in operation
  • A good and to-scale map of the city (area)
  • Allocation of routes and/or vehicles by depot, depot locations and lines used by each route to go from the depot on duty and back to the depot
  • Timetable, or if not available, approximate intervals between vehicles for each route and for each period of the day; times of departure of the first and the last runs
  • Personal familiarity with the network, as things tend to look differently on the map and in real world


  • Step one: setting the scale, positioning the layout in the file, setting options
            In the meanwhile: save your layout file
  • Step two: create routes
  • Step three: build tracks
            How to: sequence of steps
            In the meanwhile: build and input settings for switches (turnouts) and reversing/shunting points
  • Step four: place stops (stations) and timing points
  • Step five: create depots and rolling stock
            In the meanwhile: design and import user-defined vehicles
            In the meanwhile: design and place signalling systems
            In the meanwhile: place route changing points
  • Step six: define approximate schedules via settings for timing points

      Further steps:


  • Fine-tune schedules
  • Type cell text: routes, street names, stations, etc.
  • Write infotext notes
  • Place surroundings: buildings, parks, factories, etc.
  • Design and place user graphics symbols

      How to Build Tracks: a Sequence of Steps

    Assuming that you have defined and made visible the grid - and set it to match the grid on the map of the area that you use:

  • Choose the cell on the map and go to the matching cell in the BAHN layout file. Set the view to 1:8
  • Identify major straight lines in the selected cell: horizontal, vertical or 45-degree diagonal; and plan how they will go through the cell in the layout. Plan for the lines to link to the neighboring cells and convert lines going at odd angles into one of the three types above (or a combination thereof)
  • Lay these major lines using symbol sets invoked by pressing R and R>F7
  • Switch to view 1:1 and lay curves using the same symbol sets
  • Plan and lay switches/turnouts, except for the turnouts themselves, using symbol sets above and those invoked by keying O and O>F7
  • Lay switches first as trailing only using symbol sets W, W>F7, W>F7>F7 etc.
  • Input switch settings (the appropriate type, route information etc.)
  • The cell is ready - move on to the next one!
