New York City Transit President Andy Byford is opening himself up to questions on Twitter this Thursday.

He says no subject will be off limits during the 90 minute session that starts at 10:30 a.m.

Byford doesn't personally use Twitter, but will be using the handle @NYCTSubway, which has more than 900,000 followers.

The Twitter forum comes on the heels of a report the MTA may not be telling the complete truth about why subway trains are late.

According to the Daily News, transit officials were unable to determine why more than 10,000 trains were delayed in January.

They reportedly divided those numbers into 14 existing delay categories like weather, police investigations, and sick passengers.

But none of those causes may have actually been the reason for the late trains.

There were more than 76,000 weekday delays in January.

Only 58 percent of trains were on time.
