This is related to [http://trac.openstreetmap.org/ticket/4342].
Lines tagged as railway=tram now get drawn over roads, which principally is fine, as it means tram lines running parallel to roads are visible in lower zoom levels as well.
However, proper layering seems to be broken now, as a railway=tram passing under a highway=secondary with bridge=yes and layer=1 is now incorrectly drawn on top of the road.
See example here: [http://www.openstreetmap.org/?lat=49.114926&lon=8.479103&zoom=18&layers=M]
