Train Daddy loves you very much — and he loves the nickname.

The MTA and its subway chief, Andy Byford, have fully embraced the quirky moniker bestowed upon Byford by New Yorkers — employing the sobriquet in a New Year’s tweet.

Byford “is out wishing customers a happy, healthy 2020, and thanking our Transit colleagues for their hard work tonight,” New York City Transit tweeted Tuesday night, along with photos of Byford hard at work.

“From Train Daddy himself: ‘Have a great night and get home safely! Mind the gap,'” the message closed.

The British-born Byford, 54, has also indicated that he’s all-in on being the Big Apple’s Train Daddy.

“I’m looking at a full range of merch plus I’m launching a tdiddy rap label,” Byford joked to The Post when the nickname first emerged.

“Or ChuffDaddy,” he added — his wife’s suggestion — explaining that Brits refer to trains as “chuffers.”

The loving nickname for Byford began as a piece of offbeat Brooklyn street art.

In November, an anonymous Byford booster began slapping stickers showing the transit honcho’s grinning face superimposed onto the front of a subway car, ala Thomas the Tank Engine, around central Brooklyn.

Above the modern-day centaur — rendered in black-and-white, except for a pinkish hue tracing Byford’s lips — is the message, “Train Daddy loves you very much.”

In an interview with transit blog Second Ave. Sagas, the sticker’s creator said that they felt compelled to stand up for Byford amid his well-documented tensions with Gov. Andrew Cuomo.

“I really liked what Byford was doing with the Fast Forward plan and felt like he needed some recognition and love in light of that bastard Cuomo treating him like s–t,” the artist told Second Ave.

“But I wanted it to be weird/bizarre and turning him into a train and calling him daddy seemed to fit the bill,” the creator continued. “It evolved into a joke between my wife and I talking about the train daddy and how he loves all his little train babies.”

Train Daddy could not immediately be reached for comment Wednesday.
