Roof Fire at NJ Transit’s Kearny Hub Halts 10 of 11 Rail Lines

A rooftop fire at NJ Transit’s Rail Operations Center in Kearny suspended service on 10 of the agency’s 11 rail lines for about an hour Sunday afternoon, the second fire in three days to paralyze commuter rail across the New York metropolitan region. Trains stopped running shortly after 12:30 p.m. and resumed by 1:15 p.m., though 30-minute delays trailed the network for the rest of the day, according to agency alerts.

The flames never left the roof. Their reach went everywhere a New Jersey commuter rides, because nearly every line outside one Amtrak-controlled corridor is dispatched from that single building.

Sixty Minutes That Halted Ten Lines

The fire broke out on the roof of the Rail Operations Center, the facility inside NJ Transit’s sprawling Meadowlands Maintenance Complex where dispatchers monitor and direct train movements statewide. With the building unsafe to occupy, controllers had to leave their posts, and trains across the system were held in place until they could return.

“There was a fire on the roof,” said Anjali Hemphill, an NJ Transit spokesperson. “Trains were stopped for about 60 minutes until it was safe for dispatchers to re-enter. Trains are moving again.”

Ten lines went dark in both directions during that window. The suspension covered:

• North Jersey Coast Line
• Raritan Valley Line
• Atlantic City Line
• Morris & Essex Lines
• Montclair-Boonton Line
• Gladstone Branch
• Main Line
• Bergen County Line
• Port Jervis Line
• Pascack Valley Line

How One Kearny Building Controls the Whole Network

The reason a roof fire could freeze a state’s worth of trains sits in the architecture of how NJ Transit runs. The agency centralized dispatching at the Rail Operations Center, which opened in 2003, pulling control of train movements into one command floor. When that floor empties, there is no second room elsewhere that quietly keeps the lines moving.

That centralization was sold as modernization, and for two decades it has been credited with steadier, more efficient operations across NJ Transit’s four decades of rail operations. The trade-off is concentration. Efficiency and a single point of failure are the same design viewed from two angles.

The one line spared Sunday tells the rest of the story. Northeast Corridor trains kept running because that route is dispatched by Amtrak, not from the Kearny floor, which is why the busiest passenger railroad in the country stayed live while ten regional lines went silent.

• 10 of 11 NJ Transit rail lines suspended at once
• 2003 the year centralized dispatching moved into the current operations center
• 60 minutes dispatchers were locked out before returning to their consoles

Two Fires in Three Days Along the Same Corridor

Sunday’s outage landed on a region already raw from two fires in three days. Early the previous Friday, a fire between Penn Station New York and the Hudson River rail tunnels reduced NJ Transit and Amtrak service through the Friday evening rush and into the weekend, an incident our earlier reporting tied to a maintenance train that injured five rail workers and halted service across three railroads. Crews worked the tunnel through the weekend, aiming to reopen the north tube for the Monday morning commute.

The two events hit different parts of the system, which is what makes the back-to-back timing sting. One struck the brains of the network; the other struck its busiest artery.

The 115-Year-Old Bottleneck Under the Hudson

Friday’s fire pointed at the older problem. The tunnel carrying trains under the Hudson River, the North River Tunnel, went into service in 1910 and has run continuously since, making it more than 115 years old. There are two tubes, one for each direction, and no spare.

Superstorm Sandy made the aging worse. The 2012 flooding left chlorides behind in the tubes that keep corroding the structure and its electrical equipment, the kind of damage that turns small faults into service-stopping ones. With only two tracks and no redundancy, a single problem in one tube ripples across the entire Northeast Corridor.

The fix is the Hudson Tunnel Project, the centerpiece of the broader Gateway Program, which would bore a new two-tube tunnel and rehabilitate the existing one to create four modern tracks. Backers argue in the Hudson Tunnel Project’s case for new tubes that any further service cuts through the existing tunnel would carry massive economic consequences for the region and the country.

The numbers around the build are large and the timeline is long. Early construction alone is generating $19.6 billion in economic activity and supporting more than 95,000 jobs, according to the project, and the federal record on the work runs through the federal Hudson Tunnel project documents. None of it changes what riders faced this weekend, because the relief is years out and the vulnerabilities are here now.

What Riders Faced After Trains Started Moving

Resumption did not mean normal. Even after dispatchers returned to the operations center floor and trains began rolling again at 1:15 p.m., 30-minute delays were reported across the network for the remainder of the day. For weekend travelers heading to events, airports and connections, an hour of stoppage plus lingering delays scrambled afternoon plans.

The pattern matters more than any single missed train. Two fires inside three days, each capable of halting service on its own, landed on a system with thin margins and aging hardware. Riders had no way to route around either failure, because the alternative paths simply do not exist yet.

For now, the practical advice is the same as it was Sunday afternoon: check before you leave. NJ Transit pushed real-time updates through its alerts as conditions shifted, and travelers leaned on NJ Transit’s live rail advisories to know whether their line was moving.

The roof fire is out and the dispatchers are back at their consoles. The structural questions it raised, about one building running an entire network and two century-old tubes carrying a region, are still sitting on the desk.

Frequently Asked Questions

Why did one fire stop so many NJ Transit lines at once?

Because NJ Transit dispatches almost its entire rail network from the Rail Operations Center in Kearny. When the rooftop fire forced dispatchers to evacuate that command floor, there was no backup control room to keep trains moving, so 10 of the 11 lines were held until staff could safely return.

Which NJ Transit line kept running during the Sunday outage?

Northeast Corridor trains were not affected. That route is controlled by Amtrak rather than from the Kearny dispatch floor, so it stayed in service while the 10 NJ Transit-dispatched lines were suspended.

When did service resume after the operations center fire?

Trains began moving again at 1:15 p.m. Sunday, roughly an hour after they were stopped. Riders still faced 30-minute delays across the system for the rest of the day.

What caused the Friday tunnel fire near Penn Station?

An early morning fire broke out in the rail tunnel area between Penn Station New York and the Hudson River tubes, tied to a maintenance train incident that injured five rail workers and reduced NJ Transit and Amtrak service through the Friday rush and the weekend.

How old is the Hudson River rail tunnel?

The North River Tunnel opened in 1910 and has operated continuously since, making it more than 115 years old. It has only two tubes and no spare, which is why the Gateway Program’s Hudson Tunnel Project aims to build a new tunnel and create four modern tracks.
