I guess the railroad isn't the only industry having trouble with their new equipment. The number is now at 7.

Mayor Bill de Blasio’s new ferry fleet can barely stay afloat, with at least five new boats pulled out of service to fix potentially disastrous leaks — three of them still sitting in dry dock, The Post has learned.
The Coast Guard ordered repairs following inspections that uncovered “heavy pitting” in the aluminum hulls of the three idled vessels, USCG Warrant Officer Allyson Conroy said
City officials had promised the watercraft — which cost about $4 million each — would be built “with the latest in 21st-century maritime technology and best design practices.”
But sources said workers were welding metal patches onto the leaky hulls while experts scramble to figure out why corrosion was causing the 3/16-inch aluminum to fail so soon.
“There are holes the size of a pencil inside, below the water line,” said one source familiar with the problem.
“In theory, you can lose one compartment, but if you get a hole punched the size of your fist in one compartment, with the water pressure, it can implode and the compartment can sink quick.
“It can list to one side and increase water pressure on the other compartment and cause this to become catastrophic quickly,” the source added.
A crew member on the East River’s South Brooklyn route between Bay Ridge and Manhattan’s Pier 11 confirmed that the fleet has been plagued by holes in its hulls.
“We’ve had lots of little problems, mostly leaks. It really depends on the boat, but it happens,” the worker said. “The system is new — it’s all part of the process.”
