[#D: <Direction> ]

Default direction

The travelling direction the vehicle whishes to have.

This macro affects the train direction in which the vehicle is included only, if

• There is no direction parameter ( D, D1, D2 …) in the movement the picture is used
• There is no direction setting inherited for the line from the enclosing segmentation commands ( $SECTION, $GROUP,   $PATH )
• This is the first vehicle in the train, which has a [#D: ] macro, and there was no direction-dependent construct ( for example:   $DIR() ) before.
