The tram lines e.g. in Hanover should be pink, but are green. Compare to the online rendering: ​http://www.openrailwaymap.org/canvas.php?lang=de&lat=52.33390498132421&lon=9.691349565982819&zoom=18&style=electrified

Are you relating to [frequency=0] in the linked MapCSS file?

I am not the one who reported it, but a small test:

Have some object with foo=0 and validate with this:

*[foo=0] {
        throwWarning: tr("foo");
}

Note how no warning appear.
Now change foo=0 to foo="0" and validate it again.

In 9247/josm:

fix #12267 - MapCSS conditions does not handle unquoted 0 value

Such as in [frequency=0].
