Overall, it sounds like cyclists that ride the Amtrak and Metro-Link have a much better time of it then those of us who ride Los Angeles Metro (Green Line in my case)! We have one "bike-space" (where they essentially took out three sets of seats) which is also (potentially) shared with luggage and/or baby strollers.
And that is one "bike space" (two bikes can actually fit there) in the typical Metro 3 or 4 car train. No hooks, no rack . . . nothing. Just a "space." Plus, other folks can (and do) stand in the bike space, even if they don't have a bike, when the train gets crowded.
On the other side of the coin (or TAP card) one way fare is $1.50, so I can't complain (but somtimes I still do).
