A train 

The feeling of being able to accomplish anything while on adderall; often associated with a ten fold increase in productivity.

A: Hey man are you okay? What'd you do all day, didn't hear from you at all.

B: Yeah, I'm fine, just took a ride on the A train. Cleaned my room top to bottom, alphabetized my DVD's, and got all of my laundry done. AND finished that paper I put off for 2 weeks.

A Train 

A New York City subway train (the Eighth Avenue Express) mentioned in Duke Ellington's signature song "Take the A Train" and famously performed by Ella Fitzgerald. The A Train passes through Harlem, stopping at 145th Street ("Sugar Hill"), a center of African American culture during the "Harlem Renaissance" between the world wars.

You must take the A Train / To go to Sugar Hill way up in Harlem / If you miss the A Train / You'll find you've missed the quickest way to Harlem ...

"Take the A Train"
Billy Strayhorn

A Train 

A New York City subway service known as the Eighth Avenue Express. Biggest issue is when heavy traffic persists at 59th Street Columbus Circle with the D Line. This train also has 2 south terminals and 3 on rush hours, so if you are going to Lefferts Boulevard make sure you aren't on a Far Rockway train.Sometimes the R46's destination signs don't work and announcements can barely be heard so it can be a 50/50 gamble.

"This is a Far Rockaway bound A Train, the next stop is 59th Street Columbus Circle"

*few minutes later*
"We are being held due to train traffic"
*10 minutes later*
"This is 59th Street Columbus Circle"

a train 

The train that atheists ride, where no one worries about hell or sin and where science and thinking are encouraged. It's the opposite of the G-Bus.

Get off the G-Bus and ride the A train!
