Seattle-based Sound Transit set all-time annual ridership records in 2012 for boardings on its commuter trains, buses and light rail. The agency had an estimated 28 million boardings last year. Average weekday boardings topped 93,000 for the year.

The combined annual numbers were up almost 12% over 2011 and boardings on all Sound Transit services topped agency projections for the year.

"It was a great year for Sound Transit riders with more people than ever discovering how much time, money and frustration they can save by taking the trains or buses," said Sound Transit Board Chair and Pierce County Executive Pat McCarthy. "With so many more people using our services it will be vital for Sound Transit to maintain the high standards our riders have come to expect."

Here's a look at the 2012 boardings by the numbers:

• ST Express regional buses: 15. 4 million boardings, a 13% increase from 2011
  
  

• Central Link light rail: 8.7 million boardings, an 11% increase from 2011
