The MTA is planning to sue the city for failing to prevent the fire that damaged elevated Metro-North tracks in Harlem in May. The fire started at the Urban Garden Center, a garden supply store housed under the tracks in a market space that the city Economic Development Corporation manages, and was fueled in part by propane, gas, and firewood that the MTA says shouldn't have been stored there.

In a notice of claim with the city Comptroller's Office, the MTA accused the city of "carelessness, recklessness and negligence" for allowing the highly flammable stuff to be kept under the tracks without Fire Department approval.

The fire stopped Metro-North service, and caused days of delays. The Wall Street Journal reports that the MTA approved a $3 million contract this week for more permanent repairs to the tracks. Metro-North lost $2.4 million in revenue in May due to the fire, according to the paper.

The New York Times writes that steel columns installed after the blaze are currently holding up the Park Avenue viaduct, but that trains on some tracks are still traveling at half speed pending further repairs. The fixes are supposed to take until the end of November.

A mayor's office spokesman told reporters in a statement that the city has changed the way it assesses possible hazards under Metro-North and other elevated train tracks around the city.

"The city took swift and decisive action in the wake of the fire to set up an inspection regimen that continues to review these areas citywide for violations and fire hazards," the spokesman said.

The FDNY ticketed the garden center following the fire for storing propane and gas, and heating the greenhouse with propane. The fire started when a worker spilled fuel onto a still-hot generator while filling it up.

Garden center manager Alexander Gatanas told the Journal that the business has gotten rid of its propane and firewood, but is still storing mulch and fertilizer, as they are key to the trade.

"We are following the rules of the game," he said.

The MTA is a state agency that is controlled by Governor Andrew Cuomo, who is a year and a half into a petty feud with Mayor Bill de Blasio that is hurting New York City. The pissing contest dates at least as far back as Cuomo's decision to shut down the city's subway system during a blizzard in January of 2015 without consulting de Blasio or anyone at the MTA, even though trains needed to continue running overnight to keep tracks from freezing.
