line number of line S22 of <a href="https://en.wikipedia.org/wiki/Munich_S-Bahn" class="extiw" title="en:Munich S-Bahn">Munich S-Bahn</a>.
This line number sign was created in the 2006 style, which is from a time when the corresponding S-Bahn line no longer existed. The image can be used to obtain a uniform style in new texts and it can be used in the future if the line numbers are changed again.
