Last week, the departure of Andy Byford — the so-called “Train Daddy” — sent shockwaves through the city, and left people wondering about the future of the subways, which Byford was credited with getting back on track following a disastrous period of delays and service disruptions.

But Tuesday, as Pat Foye and other MTA officials came to testify in Albany, lawmakers seemed much more interested in a proposed change in bus service for Queens than talking about Byford.

“The idea that the bus redesign should be revenue neutral, r perhaps more aptly called cost neutral, does that make sense? Does that make sense in a system where we are investing billions of dollars in more money?” asked Democratic State Senator John Liu.

“Where there are needs to invest additional monies in bus service in the state of New York, we are prepared to do that, and to add service,” Foye said in response.

While there were a couple of questions about Byford during roughly three hours of testimony, it wasn’t until the end of the hearing when Manhattan State Senator Brad Hoylman focused on Byford, and what happens next for the Transit Authority.

“I don’t have to tell you he had achieved something like folk star status among straphangers. How are you going to continue to build on Mr. Byford’s work?” asked Hoylman.

“One of the things that Andy did was to leave a strong team in place. And I believe that team is going to be able to build on the momentum he has created,” Foye answered.

With a new structure taking shape at the MTA, some have wondered who will replace Byford, and whether that job will even be the same. Foye declined to provide any specifics.

“I think when we’ve got something to announce short term, we will,” Foye said.

What a difference a week makes.

If lawmakers had concerns about the fate of the subways, that was not evident at this hearing. MTA officials have said repeatedly that things will continue to improve in Byford’s absence.

Byford departs the agency February 21st.
