Where There's Smoke, There's Not Always Fire


The initial cause of the Green Line meltdown was something called an arcing insulator. Insulators are part of the support structure for the third rail and they are spread about every 10 feet along it. For them to smoke is not uncommon at Metro. To the untrained eye, the smoke can look like a major problem, but it's relatively routine and doesn't pose much of a threat, several Metro sources confirm.

But at Metro, even small, relatively insignificant problems like an arching insulator seem to regularly cascade into full-blown crises. I wanted to find out why.

Here's how a small incident gets escalated into a major even like last Wednesday. It's based on conversations with sources knowledgeable about how Metro reacts to this kind of event.

First, someone, probably an operator, saw the smoking (arcing) insulator. The operator called Operations Control Center (OCC/Central) to report the smoke.

Then, because  "[OCC has] no idea that an arcing insulator is not a big deal," OCC called the fire department, according to a source.

"These people at OCC overreact to everything and don't listen when you say it's just an arcing insulator," said the source. "They don't have a clue, and when they hear 'smoke,' their first reaction is to call the fire department. When someone who knows what's going on offers to help, it sounds all foreign to them. They have no knowledge of electricity."

A second source agreed that Metro relies too much on the fire department in these kind of situations and that it complicates everything.

"Now we've got to have a show," they said. "I'm all for safety, but you can't get sent to the ICU  every time you get a headache. Central took away any decision making from the field. They can't see, don't know what's going on and can't communicate. They default to EMT. Nobody wants to take charge, so they pass the buck to the firefighters."

A third source said "there's very little knowledge of how Metro really works at OCC. They've worked at OCC, and that's it, yet our lives and yours are in their hands, and the way Metro is set up, they make all the decisions. They'll do anything to avoid making any kind of decision, so they call the fire department and wash their hands of it all."

One source, who has been at Metro a long time, says over their career, there have been two occasions when the fire department was really needed.

The source claimed that in the not-so-distant past, arcing insulators were dealt with by sending someone into the tunnel with a sledgehammer to literally smash the insulator, ending the problem immediately. With one insulator gone, trains can still pass safely through the area, and the insulator can be replaced later, at a more convenient time, they said.

"I've seen two track guys with a sledgehammer correct [arcing insulators] in a minute or two, and it takes the fire department 30 to 40 minutes," the source said. "Now, [OCC will] call the fire department 70 percent of time time, it was the opposite 10 or 15 years ago."

Another source called sledgehammer practice "old school," saying it's probably better just to let the insulator burn out.

Both sources agreed that while area fire departments receive occasional primers from Metro on how the system works, the firefighters aren't totally comfortable in the Metro environment, adding to delays. Furthermore, fire departments usually operate methodically, which again adds to the delays.

"Their aim is not to get the trains rolling again, it's to do things by the book," said a source.

"They are not very trusting of Metro," said another source. "You blame them?"

Calling the fire department sets the table for subsequent events, sources said. Add bad radios and incompetence into this mix, and you get the the Great Green Line Charlie Foxtrot of 2013.

Just incredible. It seems the depths of stupidity at Metro know no limits.
The little subway that cried wolf.
Wait a minute. What would people be saying if smoke was reported, the fire department was not called and a people died when a fire erupted.

Did you read the story? the people calling the fire department show no discretion. Arcing insulators are a joke. Anyone with even the slightest amount of experience could identify one and react accordingly by NOT calling the freaking fire department@!

These metro sources are 100% right
when there's smoke in my house, 99% of the time it's because i left something in the oven too long. instead of calling the fire department every time, i check to see the cause of the smoke.

i don't think anyone's suggesting that metro doesn't call the fire department if there's a real fire risk.
One of the sources made pretty much this same point. Should have included it.
Tim, I'm with you on this one. If so many people at Metro are as uninformed as most of these blog posts suggest, then the people 'experienced' at handling the situation would be somewhere forced to twiddle their thumbs while the cronyism beneficiaries where clocking overtime clueless to how to identify and resolve a smoky situation. It comes as no surprise that the fire department goes by the book and does what they can to ensure the safety of the people and themselves. If I'm on a train and I see smoke in the tunnel, I'm calling 911 (if I got a cell signal). Why would anyone do otherwise when dealing with an organization that has a record of killing their patrons and employees?
I love how Metro supporters try to create false dilemmas. Do you REALLY think that the only choices are to either always mindlessly call the fire dept. over every little thing or to never call the fire dept. over anything? There's no third option that maybe involves competent people evaluating the situation and deciding whether to call the fire dept. or not?

Great. So now we’re playing Operator and “The Boy Who Cried Wolf”. It’s a good thing that the fire department doesn’t treat Metro as they do people and charge them each time they’re called to handle a situation.

Don't those insulators know that smoking is bad for their health?

(sorry)

Yeah, if an 'old school' person sees them smoking, he'll smash them with a sledgehammer! Yikes, I wouldn't want to be that insulator!
What could burn in an underground tunnel anyway? The ties are concrete and most everything else is metal. I guess some of the wiring insulation could light up...still wondering what kind of conflagration could occur.

Anyone?

+1 i love it when people use the word conflagration...it gets me SO hot...
Given the intelligence that some Metro employees display on a daily basis, I wouldn't be surprised if a couple of employees got drunk and lit fireworks in tunnels.
I've seen enough trash blowing around on the tracks in stations (plastic bags, food wrappers, newspaper pages) that it's easy to imagine this debris getting sucked into the tunnels when a train passes through.
You mean WMATA doesn't know how its own system works? I'm just SHOCKED, I tell ya!

It's only February. Betcha there'll be worse before the year is out.

Crap, now you've surely jinxed it.
Given everything we know about Metro (Shoddy maintenance, poor communications etc) I would think it would be best to err on the side of caution when it comes to smoke in a tunnel. If the Operator sees smoke and passes it off as insignificant without reporting it, that would be negligence of the highest order. Also, asking the people in OCC to make a determination as to whether the reported smoke is worth risking lives over by not calling Fire EMS seems to be unreasonable. In any building, if you see smoke, you are taught to raise the alarm and evacuate. Why should a rail tunnel be any different? It may well be a perfectly harmless smoking insulator, but it also could be a serious fire risk. How would anyone be able to make that call from OCC? I would expect the people in OCC to be able to schedule / navigate the trains so that I can get to work on time and in one piece, but not to make fire assessments based on a description of an operator seeing smoke in a tunnel.

"Why should a rail tunnel be any different?"

Because: 1) arcing insulators and the resulting smoke occur all the time; coupled with: 2) shutting down and/or evacuating trains in rail tunnels, in the dark, with no effective communications, carries a separate set of serious, injury-threatening or even life-threatening risks. Particularly when Metro's poor emergency and communications procedures mean that it can take an hour or longer for emergency responders to reach the train.

I don't have the expertise to know whether these calls could be made better either by a (well-trained, which is questionable on Metro) rail operator or OCC dispatcher. But a system that really valued safety for its personnel, customers, and emergency responders would have a system in place to evaluate which risk is greater.
That's just it. A simple message to passengers "Please have patience while we investigate smoke in the tunnel. Do not exit the train and please await official instruction." Two hours is a lot of time to spend in the dark, but how much of that time was because people chose to exit the train, therefore causing emergency personnel to make sure they were clear before restoring the power to the third rail? The answer to that hasn't been provided, but I'm certain that informed communication from the train operator would have alleviated a lot concerns of the passengers and possibly sped up the process of restoring power and getting moving again. Very basic training is not provided to employees. And it is not a system that values the safety of anyone.
You just hit the nail on the head. Metro clearly does NOT care about anyone's safety. Had they really shown any concern, the horrible accident in 2009 might not have happened. Oh but wait, I'm assuming that WMATA gives a damn, ever did give a damn, or ever will. Silly me.....
"informed communication from the operator would have alleviated a lot of the concerns" ...this statement would be accurate if the operator was being informed of what is going on......
"A show" That's all Metro is. One big ribbon cutting/PR show.
Honestly, when it comes to the lives of hundreds, if not thousands, of people in a crowded subway train that is underground, I would prefer that the fire department be called each and every time there's a report of smoke. You're asking people who are not trained fire fighters to make a decision as to whether there actually is a hazard that can put people's lives in danger. I wouldn't want to do that, nor would most people, I think.

Metro has lost all common sense when it comes to this. I saw the changes myself.

The expertise is slowly draining from the place and being replaced by nincompoops.

Arcing insulators are EASY to spot. I could teach you in a minute what one looks like.
it is very simple to identify the arcing insulators and how to go about correcting the situation.

1) train operator reports smoke or arcing insulator and gives a chain marker location.
2) second train if necessary will be told to shut off the hvac system on the train and verify it is an arcing insulator.
3) OCC then notifies track dept to respond and in the mean time trains are told to shut of the HVAC while traveling through the area and to notify OCC if situation worsens.
4) track dept are dropped off at said chain marker and allows the train to clear, then informs OCC to drop third rail power. bust out insulator in 15 seconds. notifies OCC to restore third rail power, which takes one minute with proper safety announcements.
5) power comes up, next train through picks up track dept.
6) situation taken care of. total delay to riders. 4 or 5 minutes tops.

We used to do it that way when we had OCC controllers who had any idea of the railroad and would listen to input from those on the line.
