""Greatest passenger growth and declines: The following stations had the "fastest passenger growth" as of February 2009. (The answer isn't clear on whether this is year over year or something else.) The numbers reflect percentage change and absolute growth numbers.

Growth:

1. Columbia Heights, 25.8% (11,325)
   
2. Eisenhower Avenue, 17.9% (2,292)
   
3. NY Ave/Fla Ave/Gallaudet, 16.6% (4,024)
   
4. Smithsonian, 15.8% (9,297)
   
5. U Street/AACWM/Cardozo, 14.2% (718) (This can't be correct. I've emailed Metro to verify.)"
