I'd like to take this opportunity to show off my arcane (& archaic) knowledge and point out the reference to 3211 (a line printer responsible for nearly everything printed in the '70s & '80s), should have been 2311 (an early disk drive - mid-'60s). If that's not enough for you to get the "train" references, you're not old enough, and you'd regret the time spent having it explained to you.
