When the Metropolitan Transportation Authority recently announced its decision to shut down part of the A subway line for extensive repairs, the decision upset many of the 9,000 riders who take the route each day.

But it turns out there’s another dissatisfied New Yorker: former Gov. Andrew M. Cuomo.

Transit officials had announced that part of the A train line in the Rockaways would be closed for four months, starting in January, to make repairs to a bridge that was damaged during Hurricane Sandy in 2012.

Mr. Cuomo was skeptical. In a widely distributed email, he argued that there had to be another way, comparing the situation with a similar planned shutdown of the L train to Brooklyn in 2019.

“Don’t take the bureaucracy’s word for it,” Mr. Cuomo said in the statement released on Sunday. “Convene the best experts and find a better way to get it done. Leadership matters.”

Mr. Cuomo, of course, has his reasons to weigh in.

As a potential candidate in next year’s New York City mayoral race, Mr. Cuomo has been eager to voice his views on any number of subjects, from crime to cost of living to immigration. And on this particular topic, he believes he speaks from experience.

In 2019, Mr. Cuomo halted a planned 15-month shutdown of a major subway tunnel between Manhattan and Brooklyn that would have caused one of the biggest transportation disruptions in New York City’s history, affecting 250,000 daily riders on the L line.
