The Department of Education’s transportation chief has been axed after an embarrassing slew of busing mishaps marred the start of the school year, officials said Friday.

Chancellor Richard Carranza, whose first full year in charge of city schools was immediately scandalized by the bus fiascos, will replace schools CEO Eric Goldstein with DOE operations veteran Kevin Moran.

A source told The Post on Friday that Goldstein is currently under investigation by the Department of Investigation for unrelated conduct that preceded the busing chaos. But it was the onslaught of transportation gaffes that did Goldstein in this week.

Enraged parents across the city complained of no-show buses, multi-hour trips to school and a host of other problems.

In addition, an investigator assigned to vet drivers accused officials of bypassing his approval in order to sign off on operators with dubious histories.

“Kevin Moran is the right leader to fix the problems in our busing system and ensure it’s reliable for our students, families, and educators,” Carranza said in a statement Friday. “He’s worked in operations at every level of our school system, with a track record of results.”

Moran was named senior adviser to the chancellor for transportation and will oversee the Office of Pupil Transportation through the end of the year.

“We are also launching a search for a new, permanent leader for school transportation,” the DOE said.
