Hi Greg: Great questions. If you are a rail public_transport:version=2 super-jockey, hey, polish them up to a firm buff and we'll marvel at their brilliant shine!
However (and this is pedestrian me), I make "better" progress (higher quality data, at the expense of being slower) following roughly these steps to get to version 1, first. Though these ordered steps are not strictly required, after much experience, I find this flow works and "teaches/practices me into becoming a better JOSM rail editor" (and others watching in the map, and progress in the wiki...) as I go: 1) Tag the rail infrastructure correctly with railway=rail (or light_rail, subway, tram, monorail...). If it was TIGER-imported, change its name=* tag to operator=* and if you know it, add a name=* tag (like XYZ Subdivision or Orange Line Light Rail). Set a usage=[main, branch, industrial...] tag. Don't include service=siding, service=yard, service=crossover, service=spur in route=railway relations, just the "main" line (even if it is tagged usage=branch). 2) Gather same-infrastructure, same-name, same-operator, same=usage, "in the same subdivision or track set" into one route=railway relation. 3) If not light_rail, subway, monorail or tram, make a route=train relation which has the elements of that route=railway relation, plus railway=station nodes. (If tram, they might be rail=tram_stop nodes...there is also platform tagging, which is for v2, we are getting there). With those steps, you've made a route=railway (important!) as well as a v1 train route. As for extending these to v2, that's more complex and is outside the scope of a talk-us post, I'll not do it here, we have wikis for this. "Starting at the top" (national passenger rail) is https://wiki.osm.org/wiki/Amtrak. There are several state Rail wikis, a simple one is https://wiki.osm.org/wiki/New_Mexico/Railroads, a medium-complexity one is https://wiki.osm.org/wiki/South Carolina/Railroads, a ridiculously-complex one is https://wiki.osm.org/wiki/California/Railroads. These are usually about 75%-80% descriptive of route=railway relations (the underlying infrastructure, which carries both freight/industrial traffic and sometimes also passenger traffic) and maybe 20%-25% descriptive of route=train (or other passenger rail, like tram, light_rail or monorail). See https://wiki.osm.org/wiki/Relation:route (train, light_rail...) wiki to get to v1, and https://wiki.osm.org/wiki/Relation:public_transport to grow these to v2 (underway now all over the world there are v1 train routes in OSM).
