The MTA has suspended the high-paid railroad boss who got a promotion even after his underlings reported photos of him in blackface.

Officials confirmed on Thursday that they have put general supervisor Richard Ranallo on ice “indefinitely” by order of Metro-North president Catherine Rinaldi.

“He’s being withheld from service indefinitely while we assess our options,” said MTA spokesman Jon Weinstein.

The agency will pay Ranallo while he’s suspended, said Weinstein.

Ranallo, who is white, was a supervisor of electricians when he attended a 2013 Halloween party as a black lawn jockey. He painted his face black and wore a blue-and-white checked jockey uniform and cap and carried a railroad-style lantern.

The photos were posted on Facebook, and workers told higher-ups, but they promoted him to the role of general supervisor of Metro-North third rail electricians anyway. He made a total of $246,255 on the job last year.

MTA chairman Joe Lhota on Wednesday decried the worker’s conduct as racist and condemned the Metro-North bosses who promoted him. He and Rinaldi claim they didn’t know about the situation until an expose by NBC 4 New York this week.

Lhota said agency officials were going to see what kind of discipline Ranallo’s labor contract allowed. He and Rinaldi also said they would work on creating a culture in the agency where workers could feel more comfortable coming forward about racist incidents.
