A rather complex parameter which determines and controls foreground, background and temporary backgroun pictures.
Multiple individual pictures must be separated by a comma:
With these possibilities one can develop background scenery which is independent of the screen width or resolution settings.
If the interval format is used, the default value for the left position is the left side of the line, the default value for the right side is the right side of the line ( the width of the line can be shorter as the screen width, if the movement or one of the enclosing segmentation commands have a
Some pictures perhaps should fit an area, but the main picture cannot be repeated or shown from the middle - as a main building of a factory, or a special point in the catenary - the change of the wires, or the switch box for the lead-in of the current. The formats

The picture SAVTE_FG for a SAVTE interurban is repeated as often as necessary to cover the entire width of the screen. In the above example, the omission of the two starting and ending points is equivalent to setting these values as the screen edges: (
If you wish to experiment by using the above example in a Timetable file, you should not forget to modify the
Two signals of the same type are placed in close proximity to each other on the screen, at 30% of the screen width. The first is for trains travelling right to left and is offset from the 30% point by 4 pixels. The second signal is mirrored with
Let's take a look at a station platform! The PLF.. pictures are pieces of a station platform. The primary element is in the middle line: a sequence of individual pictures and pictures which are always repeated five times next to each other, each of which consisting of a piece of platform and a piece of platform with a post. This grouping is repeated three times in succession and in this way makes up the part of the platform which is covered with a canopy. The pictures which comprise the first and last lines depict the ends of the canopy as well as the parts of the platform which are not covered by the canopy. The entire platform as a unit is placed with its middle aligned to the centre of the screen:
As you can use for all the repetition counts, element selections and placements (positions) random choices, one can write foreground and background expressions delivering various background pictures.
