New York City Transit President Andy Byford's first general town hall on Tuesday drew a big crowd in Brooklyn.

People packed John Jay High School in Park Slope to discuss Byford's plan to modernize the transit system.

It calls for a multi-billion dollar investment that includes new signals and more accessibility.

Many questioned how Byford plans get both the governor and the mayor on board with funding.

But he said his main concern is serving the public.

"I really enjoyed forums like this because you get to sense the passion of the people who at the end of the day pay your wages. So I've never believed that I should sit in my office. You should be out there finding out what it is that people want from transit," Byford said.

Under Byford's plan, accelerated signal work will take place on weekday nights and weekends to expedite the process.
