#BREAKING: Sources tell NY1 New York City Transit Authority President #AndyByford has resigned.

Congrats to our pal #AndyByford on becoming the new commissioner of Transport for London. Fantastic at karaoke, but even better at being the #TrainDaddy.

A sad goodbye to #traindaddy. Here's what New Yorkers had to say about #AndyByford's sudden resignation https://t.co/x5dus6dnjC

“Last month, the on-time performance was 83%, which is not just unbelievably good for NYC transit, that’s good anywhere you go...We need to maintain that progress and improve upon it," said @FeinbergSarah, who was named interim transit president as #AndyByford stepped down.

#AndyByford is the new EVP of High-Speed Rail for Amtrak. The dream may finally be coming to life, folks.

@TfL @pedalmeapp Dear @TfL, Why are you advertising this private company? This company works in direct competition with drivers for whom you regulate. This promotion affects my livelihood. @UnitedCabbies @UTAG17 @davidkurten @Councillorsuzie @KeithPrinceAM @ShaunBaileyUK #AndyByford

So, it’s Mayors Question Time at city hall (by zoom) today Here’s my question Why are TfL managers allowed to completely ignore important questions from T&PH licence holders @KeithPrinceAM @davidkurten @Councillorsuzie #andybyford

When it comes to @andybyford, he is a class act! He didn’t become combative when asked the question like Foye did. Foye don’t care about enforcement as long it doesn’t touchdown in Port Washington.

Some say…. Criminal negligence #TFL allowed UBER to operate for 9 YRS #ILLEGALLY undermining Public Safety Who is responsible .? #JohnMason #LeonDaniels #GarrettEmerson #PeterHendy #MikeBrown #AndyByford #HelenChapman Truly appalling

Ok @MTA uptown 2 train car #6381. What’s the new plan? #andybyford

On behalf of this packed train, we’ll miss you #AndyByford.

#AndyByford actually cared about us #bus & #subway riders unlike the #MTA board or Gov. #AndrewCuomo, who made the #NewYorkCity Transit president's job impossible; #TrainDaddy will be missed~! https://t.co/pWwQHy6wST

#video #masstransit groups call on ⁦@NYGovCuomo⁩ for specifics on subway repair/maintenance following resignation of #AndyByford ⁦@1010WINS⁩

It has been a day. Thank you, #AndyByford, for transforming the way each of us approached our jobs, and for giving this historian the privilege of documenting the most exciting and important period in recent Transit history.

This never should have happened. We need to keep the keepers...@andybyford was a keeper...

New baskets to prevent bolts from falling from the “els.” @MTA @AndyByford @1010WINS

#andybyford aka #traindaddy truly will be missed. One of the great leaders ever.
