I'm so used to riding Japanese trains, I wanted to try an American train

I have been riding Japanese trains for so long, I wanted to experience riding an American train (California).  It's a bit interesting, much different.  But it's good to see many people riding on the trains but not sure if I'll be alive by the time the high speed railway in California is completed.
