MIAMI -

Tri-Rail ridership topped four million in 2012, the South Florida Regional Transportation Authority (SFRTA) announced Monday.

The 4,072,549 riders was only exceeded in 2008, when the Tri-Rail carried 4,303,509 people.

SFRTA credited employment and high gas prices for the amount of riders.

SFRTA also said it plans on offering hourly service on the weekend beginning in March.
