A most excellent suggestion, hanser, and at first glance, a well-structured OSM thrust forward for this concept: I am enthusiastic. Please keep up this sort of good communication!
Just yesterday I left off of our Caltrain wiki [1] the so-called "6-trains" on its Schedule [2] in preparation for what will be called "Blended Service" (future California High Speed Rail shares "commuter rail" tracks upgraded to what in the USA are Class 6 track, 110 MPH / 176 km/hr) known as the "Northern Bookend" in the San Francisco Bay Area's big upgrades to rail over the next decade. The reason I left off the "6-trains" from this train wiki table is because these aren't trains. (During weekend construction of new electrification towers, substations, et cetera). Here (California, USA), we don't call these "Ersatz" or "Replacement" service for the trains, we call these "bus bridges." With this, OSM will have a way to describe these "acting like train routes but are really bus routes." They do have their own "special purpose" signage, paint-on-pavement (sometimes looks like shoe-prints-in-paint) and other "route navigation aids." I look forward to a well-designed proposal and/or the emergence of sensible tagging strategies after this sort of consultation with the greater community, so, Thanks for bringing this up!
