WMATA General Manager Richard Sarles announced at today’s board meeting that he will retire, effective January, 2015.

The move comes as a surprise, since in 2013 Sarles agreed to a contract extension that would have kept him on the job until 2016. But not too much of a surprise: He’s 70 years old and has always said he didn’t intend to stay at WMATA long.

Sarles took charge of WMATA in 2010 and oversaw a significant rebuilding and safety-related overhaul of the transit system.

WMATA board chairman Tom Downs says the agency will conduct a nationwide search for Sarles’ replacement.
