14-Year-Old Turns Tram System Into Personal Train Set

F-3582 writes "By modifying a TV remote a 14-year-old boy from Lodz, Poland, managed to gain control over the junctions of the tracks. According to The Register the boy had 'trespassed in tram depots to gather information needed to build the device. [...] Transport command and control systems are commonly designed by engineers with little exposure or knowledge about security using commodity electronics and a little native wit.' Four trams derailed in the process injuring a number of passengers. The boy is now looking at 'charges at a special juvenile court of endangering public safety.'"

how many other "systems" like this?

[yagu]

I know some kids who are extremely bright, curious, and for lack of a better description, "like to experiment". Any one of these I think could have done the same thing, and with completely innocent (though mischievous) intent. For playing with such big toys in such a fashion there should be repercussions. But the kids I know who also could have done something like this would be much more on track with thinking about how they're moving switches than about what moving those switches implies.

However, I'm led to a different train of thought. What other systems are out there created in the same context, i.e., with little thought to external interference? I'm betting there are a "few". I wonder that in the process of designing something like this if we must pay more attention to the possibility of outsiders tinkering. I hope France's TGV has a bit more built in checks and balances than this. I hope the new Boeing 787 has more security built in than this [news.com.au].

I actually think (and hope) this kid's imagination and curiosity somehow gets channeled rather than squashed. He actually sounds like he could be a contributor. Of course, he's at least grounded for the next month.

I'm proud for the kid in the sense that he put his mind to work, but at the same time, no points for lacking discretion, and a good sense of responsibility. And I don't think he should get a free pass just because he is a kid. If he is smart enough to do what he did, I think its entirely reasonable to assume that he had the capacity to know what the effects may be.

When the trams started behaving strangely, the authorities suspected outside interference and contacted the club leader for any information. The club leader recalled this strange guy asking too many questions, and the rest is history.

Re:how many other "systems" like this?

14 year olds are young, but not so young to not realize that swapping train tracks around will affect what happens to trains when they reach that section of track. They might not follow that train of thought(pun intended) through to what the actual aftermath may look like, but it's no stretch of intelligence to conclude that a massive train moving at significant speeds will have a significant consequences when directed somewhere unexpectedly.

Not that I'm recommending dire consequences for the boy, I'm just saying that there is probably some malicious intent here, though he probably didn't calculate the magnitude of his mischief either. I'm envisioning something like: "I'm gonna screw around with this and it'll be funny watching them try to fix i--*FOOM*...oh...wow...shit I better go".

(And jeez, whoever designed that system that way is going to have a whole mess of flying poop coming their way).

Re:

[SleptThroughClass]

As a 14 year old I was quite aware of what would be involved with a train changing tracks, but that is because I actually had studied trains and was consciously aware of the physics involved in their movement.

Other Similar Systems: Signal Pre-emption

[Palal]

In the US many places with newer traffic signal circuitry (at least on the west coast) have something called Signal Pre-Emption [wikipedia.org].

This allows emergency vehicles to by-pass traffic lights by turning them green. It uses an IR transponder on vehicles, and an IR receiver on lights. When a certain frequency (pulse) is sent out from the vehicle and picked up by the receiver, the light turns green.

Before you try to build a device to do that I want to say 2 things:
1. Devices are available on the 'black market', and
2. Every time this signal gets sent, it gets recorded in a log. There have been cases of people getting caught using these and the fines are hefty.


The same system is used, called "Signal Priority" can be used by buses to hold the light green or trigger an early green in various circumstances. (Basically this involves sending out a frequency that's different from Emergency vehicles.

I bet that Lodz uses a similar technology for its trams, but maybe they thought nobody could figure it out, so they simply went with security via obscurity (or whatever the term for it is).

Czech Republic has a single system (as in same system type, not same transponders) in the entire country for its trams and trolley buses and uses something similar to your car key remote.

If anyone manages to figure out how the signal pre-emption works, please post details online :).

Re:Other Similar Systems: Signal Pre-emption

[Daniel_Staal]

Some places have a more inteligent system: The signal turns the light Red (in all directions), and the emergency vechicles just go through the red lights.

Works just as well, and less suceptable to hacks. (Not impossible of course, but less chance of people doing it for their own benifit.)

Re:

[Lao-Tzu]

The downside to that approach is that emergency vehicles encounter cars stopped at a red light at every intersection. Where I live, drivers panic when an emergency vehicle approaches, move their car six inches towards the side of the road, and don't realize they should go through a red light to clear the roadway.

Re:Other Similar Systems: Signal Pre-emption

Those people that panic and don't move promptly should have their licenses revoked.

This whole thread is pissing me off. "He was young and didn't know what he was doing..." BS. If the kid is smart enough to hack into a system, he's easily smart enough to know how much a train weighs and what damage a train derailment will cause. Send this kid to jail!

Secondly, I hate when people excuse bad driving as normal. It's not acceptable. If you don't clear the intersection when emergency vehicles are coming, you shouldn't be driving, period. If you consistently drive 5mph under the speed limit, your license should be revoked. If you can't PARK YOUR CAR without extreme effort, license REVOKED! If you took licenses away from all the people that shouldn't have them for safety reasons, there would be 50% fewer people on the road, AT LEAST.

I hate people.

Road rage much?

[PhxBlue]

Now, I'm all for people driving the speed limit, maybe a little more. But legally, the speed limit is an upper limit, not a lower limit. And people who drive like the speed limit is just a guideline tend, in my experience, to be more prone to road rage than those who actually obey it.

So, if more than 50% of the people are kept off the road because you don't like how they drive, perhaps they should round YOU up, get rid of YOU, and drive as they see fit without interference from micromanaging busy bodies who think we're obligated to operate in a way that you can predict and write down?

You know, there have been numerous suppressed studies demonstrating that road rules and signs actually make driving less safe because they give a false sense of security. I don't have a link at my fingertips, but there have been several of them done. The safest way to structure roads is to remove all signs and controls, and force people to remain interactive with the environment rather than being hypnotized into routine. The reason the highly structured and regulated road systems continue is because they are an industry with an interest in self-preservation, and a cash cow for government, not because they are a good way to do things.

Re:Other Similar Systems: Signal Pre-emption

[jonbrewer]

Lodz has had electric trams since 1898 - and while it's not likely any of the original track or switches are in use, the system is not new. Turning at too rapid a rate will cause derailment. I've seen a fair number of older generation trams derailed on similar Polish systems, especially around the old town of Krakow. Somehow I doubt that Lodz have a spanking new fleet of low-floor trams that have required system-wide track upgrades to run. I imagine the trams that derailed were built in the 1960s.

As for the engineers being "grossly incompetent", I really don't think so. I wouldn't be at all surprised if the system hacked was decades old, designed by folks who had no reason to think that anyone would ever have the means or desire to circumvent the system.

(FYI those 1960s electric trains are far better transport than any diesel bus I've ever been on, and the new low-floor trams are like something out of a sci-fi movie!)

True, though the systems I've seen that operated this way had another light (flashing strobe, all directions) to indicate that an emergency vechicle was coming.

While he is young and might not be held to the same standard of foresight as an adult, still his behavior cannot be excused as merely impulsive considering the time and effort involved. Even if he isn't held fully accountable for endangering lives, still he had to know he would be causing considerable disruption.

I'm curious, though, about the details of the tram system in question. The article describes a tram operator trying to go one way while the track pushed him the other way... so I assume these are not strictly rail-following vehicles (like trains) that have only an accelerator and a brake?

Re:

[eebly]

Many tram systems have operator-controlled switches. In the old days (and still in some places, like Prague) switches are set by an operator manually. This system appears to basically be the same thing through proximity IR control.
On railroads, switches are mostly controlled from a central dispatch office.

I'm surprised nobody has asked the obvious question. Switches normally switch between two tracks. How does switching a train to a different track cause it to derail? Collide, sure, but derail? Sounds like a design problem to me... or a whole lot of design problems if it is possible for it to switch when a train is in the middle of the switch, as I suspect occurred. There should be safety interlocks to prevent switching from even being possible as long as a weight sensor at the switch is depressed.

It strikes me that this kid not only found a security flaw in the system, but also found at least one very serious safety flaw that could have occurred due to electronics glitches even if he hadn't done this. It could have ben a lot worse, particularly if those same switching systems are used for any high-speed trains....

Re:

Re:New terrorist plot for TV

[joebok]

Have you never had a train set? A switch will have one pair of rails on one side, and two pairs of rails on the other. If you are coming to the switch from the side with one pair, you won't get derailed - you'll just go to one or the other output tracks. But if you are on the other side of the switch it has to be set right to get your train back to the single pair side. If the switch is set to route traffic from the other side rail then you would derail if you didn't stop.

I'm sure there are visual indicators if you are heading into a situation where the track ahead isn't switched correctly (my train set had red and green lights), but it is easy to see how there could have been derailments if somebody was running amok with the switches.

Tram line 21 runs east to west.
Tram line 19 runs east to west on 21's tracks, then turns onto a north-south track heading south.

Kid overrides with a left, lead car turns left.
Kid stops overriding, the junction again sees the signal on the tram to switch to turn right, and the second car goes right, causing a derailment.

In the US, most remote junction switches have a fail-safe that prevents the tracks from switching if there's a car over the junction, thus preventing driver error or malicious external elements from causing a derailment by making the train go in 2 directions at once. Apparently no such fail-safe is present on the systems in Lodz (pronounced 'woodj' in Polish).

• It's more expensive - you'd be running more actual track on lines that service the same areas.
• It's more expensive - you'd be building stations and track beds much larger than they'd need to be.
• It's more expensive - now every train has to service every line instead of having a centralized line that services many with various offshoots.
• if something goes wrong you

scary genius

[techpawn]

It's fun to hear about these kinds of events if no one got hurt. But, at th same time it's rather frightening the though of someone with an intellect like that with a lot of time on their hands and no productive outlet to use it.
Think what could be accomplished if people like this where given access to what they needed and had the same motivation when it came to curing cancer.

What evidence do you have that there was "no productive outlet to use it"? The kid had the time and the knowhow to do this, and you think this was somehow his only choice for expression?

I doubt that.

Why is it that...

[Anonymous Coward]

Why is it that facility operators, be it trains, power plants, oil refineries, or anything have pathetic security, and when something does happen, they blame it totally on the perp who likely never had to confront even a single lock, much less a guard?

Makes me wonder if countries should have a special regulatory team whose job it is to attempt break ins on a regular basis to various areas, and levy fines to organizations failing compliance. Only problem is areas where people shoot to kill... telling a tiger team from a genuine trespasser/burglar/criminal before pulling the trigger.

If the team is seriously concerned about being shot, I think it's safe to give that facility a stamp of approval without even attempting a break in.

Fire the safety department

[alextheseal]

The whole safety department of that tram line should be fired. A system hackable via a TV remote and unencyrpted signals subject to relay attacks should not be deployed ever. They should be sacked for having allowed it. Same goes for the "traffic light" systems here in the US with the same flaws. Course I didn't RTFA so maybe he even cracked the encryption. In which case only sack the designer of the encryption.

Yes, there's an RF remote for the thing

[Animats]

This is a street tram switching system similar to the Elektroline [elektroline.cz] system. It's not a full signalling system with interlocking. The tram driver is in control, and has an RF transmitter which can control switches. The current generation, the "TRAMVYS 6K", is an RF transmitter on 433.9 or 868.35 MHz. Normal range is very short, about 2M, with the transmitter down on the front truck of the tram and the receiver buried in the road. But it could probably be triggered by someone at the side of the street with a suitable transmitter. This system is interlocked so that the switch can't change position underneath a tram.

That's current technology. Older systems are much dumber [google.com]. Some of this stuff is at the garage-door-opener level of RF devices. The Lodz tram system dates from 1898, so they have lots of legacy trackwork.

[GiMP]

It is interesting that you note the distance required. It isn't mentioned at the Register, but the Polish news sources have said that he was riding inside of the trams that were being controlled.

Where are those engineers who designed that system

[140Mandak262Jamuna]

I have a hunch they decided there is no money in building highly insecure hardware systems and moved on to write highly insecure software systems. No prizes for guessing their current employer.

Not an Engineering Problem

[asphaltjesus]

Let's all do a reality check.

1. Engineering was likely given a number of constraints that can not be ignored. For example, build it in 6 months at a final BOM cost of $Y.

2. Picture a small hill with the railroad purchasing agents on the top. On one side is the manufacturer of switch, on the other, the boy. Sh!t rolls downhill onto both parties.

It's a pity the boy has to be made an example of.

He could have done better..

[DigitAl56K]

Four trams derailed in the process injuring a number of passengers.

I know he hacked this together out of a remote control, but that's a horribly inefficient process he created - surely it's possible to injure the passengers without derailing the trams! ;)

This will lead to a flip ending

[elrous0]

Between "Die Hard 3" and "Unbreakable," you just KNOW Bruce Willis and Samuel Jackson had to be involved in this somehow.

wait, what?

[nuggetman]

Poland is using IR to remote control their tram switches? That's just asking for trouble.

Lucky for the kid he's not an American

[BobMcD]

If he had done this in the US he'd either have been shot to death or in Gitmo by now.

If only this could somehow be spun into a funny joke, but it is too close to the truth, unfortunately.

Yeah, Poland is so backwards. In the US, we don't need teenagers to derail our trains [wptz.com].

Imagine what chaos aspiring electronics buffs will be able to create with Wii controllers!

Fortunately more useful things like an interactive whiteboard [blogspot.com] for $40. The only problem I've had is trying to get my hand on a Wii Remote to try it out but the idea is brilliant...at least if you are a professor: I can teach them physics at the same time as using physics to teach!

Uh. Sounds about right... ;-)

How exactly is this a troll? That's quite... natural.
Or are you going to tell me that an american, a ruskie or a german would reflexively act differently? For those who failed to get the parent's joke, there are some backwards islands where people drive on the wrong side of the road...

Long ago, when sailing ships ruled the sea, this captain and his crew were always in danger of being boarded by pirates from a pirate ship.

One day while they were sailing, they saw that a pirate ship had sent a boarding party to try and board their ship. The crew became worried, but the Captain was calm.

He bellowed to his First Mate, "Bring me my red shirt!"

The First Mate quickly got the Captain's red shirt, which the captain put on. Then he led his crew into battle against the mean pirates. Although there
