Taking your bike to work? It can get crowded! Know your schedules so you won't be late to work if you get booted from the first train because they cannot accept any more bikes! Source: I am a bike
When you're rushing to make the baby bullet and the doors close in your face, I'm here to cheer you up. Good music is like a natural endorphin booster!
While in principle the clipper card saves time, in practice it can be a pain -- esp at rush hour and with few validation stations, and if you need to tag-off before BART transfer at Millbrae.
If you're not on a bike PLEASE keep moving to the next cars!! First car is the bike car and it takes forever to get on waiting for passengers on foot to get on first.
If you use Clipper card with monthly pass, and travel out of your monthly pass zones, you'll have to purchase a paper "zone upgrade" from the ticketing machine.
if you're on foot don't wait in line with the bikes / if you're biking, line up close to the front of the train. No cutting! Normally 15bikes should be able to get on north after 8
