so if the first train is supposed to start from Union at 5:30 am, then why when I showed up at 5:12am today, did it say next train in 33 minutes.

if you are going to advertise something, make sure it is right. GO may have gotten away with operating with a schedule that really did not mean much, but this is an airport train that should run on time, all the time.

also, why have your cafe open at exactly the same time as the first departure. how can someone get a coffee for the 5:30 train if you say you don't open until 5:30.....

15 minutes may seem like nothing in the am but when you are on a 7am flight, 15 minutes actually means a lot.
