90° curves

[edit]
  • As always, note that BSicons are normally named from the driver's perspective (i.e. the perspective of someone looking down the line from the front of the train), so a "right turn" icon from the viewer's perspective should look like a curve from the top of the icon to the left.
  • Other separate pairs can be made by overlaying their elements, or by using the junction icons (see BSicon/Catalogue/junctions).

45° curves (ÜW)

Examples
STR2\STRc3
STRc1\STR+4

STR2\STRc3
STRc1\STRl+4

ABZg2\CONT3!~ÜWu3
ABZg+1u\CONT4

Note: the kSTR icon set works better for
large 90° curves and adjacent "S" bends:

kSTR2\
kSTRc1\kSTRl+4
kSTR2\kkSTR2\kSTRc3
kSTRc1\kkSTR+4\kSTR+4

This category contains icons originally created for flying junctions (in German: Überwerfungsbauwerk), but can also be used for broad-radius curves and other configurations. All these icons connect at a corner with the line running at a 45° angle.

Curves

[edit]

Basic curve icons use the STR root with suffixes.

  1. If the track comes from the top and goes to the bottom, no additional suffix is required.
    STR
  2. If the track comes from the top and goes to a position on the side, a single suffix to determine the direction is added.
    STRr
    to the right
    STR3
    to corner 3
    STR1
    to corner 1
  3. If the track comes from a position on the side and goes to the bottom,
    1. a "+" is added to indicate "coming from";
    2. a single suffix is added to indicate the origin.
    STR+r
    from the right
    STR+3
    from corner 3
    STR+1
    from corner 1
  4. If the track comes from a position on the side and moves to another position on the side, we add
    1. a single suffix to indicate the "to" direction (this suffix must be the one closest to the bottom);
    2. a "+" to indicate "coming from";
    3. another suffix to indicate the origin.
    STRr+4
    to the right from corner 4
    STRl+4
    to the left from corner 4
    STR2+r
    to corner 2 from the right
    STR2+4
    to corner 2 from corner 4
    STR2+1
    to corner 2 from corner 1
    STR2+l
    to corner 2 from the left
    • Note that the + is omitted if the track starts and ends at the same "level" (i.e. top or bottom).
    • For lines running across from left to right or vice versa, the suffix "q" is added.
    STR14
    corner 1 & corner 4
    STR23
    corner 2 & corner 3
    STRq
    left & right


Interruption

[edit]
Examples

Connecting to a line
uSTRc2\gSTR3+1
gLSTR+1\uSTRc4
uLLSTRc2a\gSTR3+1
gLLSTR+1\uLLSTRc4a
uSTRc2\STR3+1
LLSTR+1\uSTRc4
4
5
Connecting to another interruption
uLLSTRc2\gLLSTR3
gLLSTR+1\uLLSTRc4
uSTRc2\LSTR3
LSTR+1\uSTRc4

There are two versions of 45° interruption (Lücke) curves:

  • The LSTR group have a straight line at the corner, and are designed to connect with a solid line with two regular STRc* corners (1).
  • The LLSTR group have a quarter of a dot at the corner, and are designed to connect with a solid line with LLSTRc*a/e corners (2), or with another interruption with two LLSTRc* corners (4).

In the examples to the right the green illustrates the correct configurations (1, 2, 4), and the red the incorrect (3, 5). (In all cases the corner icons are displayed in blue for visibility.)
