Lambert is currently in his 35th year with Metro. He became interim CEO after the departure of George Greanias in late 2012. Before that, he was an executive vice-president, and he also spent 29 years as Metro's police chief. So how does a law enforcement background help in running a transit agency?
"When you're the transit police chief one of the things you want to make sure you understand is, how you're supporting the operations you're there to support. So I've often tried to learn as much as I can about how a transit system works. In order to serve that, in order to secure it, you've got to understand how that system operates, how the projects are developed."
And one of Metro's big projects this year is a "re-imaging" of Houston's bus system to provide more frequent service.
"What we're really looking at is, looking at employment changes, looking at demographic changes, looking at how we can put a more high-quality, high-frequent service on the streets."
Before Lambert officially gets his new title, he and Metro's board need to hammer out a contract.
