A map of the US showing the potential changes to passenger rail service due to the Corridor ID Program

A New Era For US Passenger Rail?

Here in the United States, we’re lagging behind the rest of the world when it comes to shiny new passenger rail, despite being leaders in previous centuries. The Federal Railroad Administration (FRA) has just released a story map of how the US could close the gap (a little).

A new blue and white high speed train crosses a brick bridge. There is what looks like a park beneath and a cityscape in the background.The Corridor Identification and Development (CID) Program is a way for FRA to provide both funding and technical assistance as corridor sponsors (mostly state Departments of Transportation) evaluate either new intercity service or expansion of existing services. While it isn’t a guarantee of anything, it is a step in the right direction to rebuilding passenger rail capacity in the US.

Some cities would be getting rail service back for the first time in decades, and perhaps even more exciting is that several of the routes being studied are for high speed rail “primarily or solely on new trackage.” As any railfan can tell you, vintage rails aren’t the best for trains going fast (sorry, Acela). With recent polling showing strong public support for the build out of high speed rail, it’s an exciting time for those who prefer to travel by rail.

We don’t think you’ll be able to ride a gyro monorail, nuclear-powered, or jet train on these proposed routes, but we do hope that Amtrak and FRA are looking to the state-of-the-art when it comes to those high speed alignments. While you’re eagerly awaiting new passenger service, might we recommend this field guide to what all those different freight cars going by are for here in North America?

A warehouse with concrete floors and at least four subway car rails running off into the distance. On the rails are dozens of R142 series subway cars with refurbished trucks in the foreground. People are visible on the floor moving a truck, and one man is in a bright yellow crane above everything watching what happens.

Overhauling Subway Cars Is A Big Job

Subway cars have a tough life. Moving people through a city efficiently underground every day and night takes a toll on the hardware. To keep things running efficiently, NYC rebuilds its cars every six years.

The enormous job of refurbing a subway car back to factory spec happens in one of two yards, either in Brooklyn or Manhattan. The cars are pulled off their 16,000 lb trucks, and treated to an overhaul of their “doors, windows, signage, seats, floor tiles and HVAC.” The trucks are inspected and wheels can be reground to true at the six year mark; they get all new wheels every 12.

Once everything is repaired, the shiny and like-new components are inspected and reassembled to go back out on the line. While it’s no small job, the overhaul shops can process over 1,000 cars in a year to keep things running smoothly. Before the overhaul program was introduced in the 1980s, NYC subway cars typically experienced failures every 16,000 miles, but between the scheduled maintenance and other advances that number has soared to an average failure rate every 140,000 miles.

For a somewhat less official use of underground spaces, how about this Parisian secret society? If you really want to bring the subway home, how about making an old subway seat into a chair? If you need something more light-hearted, you should really checkout this 90s subway safety video from LA.

Hackaday Podcast Episode 250: Trains, RC Planes, And EEPROMS In Flames

This week in the Podcast, Elliot Williams is off at Chaos Communication Congress, hearing tales of incredible reverse engineering that got locomotives back up and running, while Al Williams is thinking over what happened in 2023. There’s a lot of “how things work” in this show, from data buoys to sewing machines to the simulated aging of ICs.

Whether you’re into stacking bricks, stacking Pi Picos, or stacking your 3D prints to make better use of precious bed space, this episode is for you. Enjoy.

This is your last chance to download a new podcast this year. Take it!

Polish Train Manufacturer Threatens Hackers Who Unbricked Their Trains

A week ago we covered the story of a Polish train manufacturer who was caught using software to brick their products after they had been repaired by in independent railway workshop. Now 404 Media has a follow-up story with more information, including the news that the hackers responsible for the discovery are now being threatened by the manufacturer.

The more we learn about this story the more interesting it becomes, as the Newag trains in question began failing after service as far back as 2021. In desperation after services were affected by the number of non-functional units, an employee searched online for Polish hackers and found a group called Dragon Sector. The group was able to find the issue, and are now being threatened with legal action by the manufacturer, who are citing possible safety issues.

It’s clear from where we are standing that Newag have been caught red-handed in some extremely dubious practices, and seem to have little sense of how their actions might not be the best in terms of protecting their reputation. We are guessing that the European regulators will become very interested in this case, and that meanwhile the order books of a company which puts DRM in its trains will start to look very empty indeed. You can catch our original coverage as the story broke, here.

The Deere Disease Spreads To Trains

If the right-to-repair movement has a famous story, it’s the familiar green and yellow John Deere tractor. Farmers and mechanics have done their own repairs as long as there have been tractors, but more recent Deeres have been locked down such that only Deere-authorised agents can fix them. It’s a trend that has hurt the value of a second-had Deere, but despite that it appears to be spreading within the machinery world. Now there’s a parallel on Polish railways, as Polish-made Newag electric passenger trains have been found to give errors when serviced by non-Newag workshops.

At the heart of the problem are the PLCs which control all aspects of a modern rail traction system, which thanks to a trio of Poland and Germany based researchers have been found to play a range of nasty tricks. They’ll return bogus error codes after a set date which would presumably be reset by the official service, if the train has been laid up for a while, or even if they are detected via GPS to have visited a third-party workshop. Their work will be the subject of a talk at 37C3 which should be worth watching out for.

It will be especially interesting to juxtapose the reaction to this revelation with cases such as the Deere tractors, because of course Poland is part of the European Union. We’re not specialist EU competition lawyers, but we know enough to know that the EU takes a dim view of these types of practices and has been strong on the right to repair. Who knows, Polish trains may contribute further to the rights of all Europeans.

Polish Railways Fall Victim To Cheap Radio Attack

Poland’s railways have recently come under a form of electronic attack, as reported by Wired. The attack has widely been called a “cyber-attack” in the mainstream media, but the incident was altogether a more simple affair pursued via good old analog radio.

The attacks were simple in nature. As outlined in an EU technical document, Poland’s railways use a RADIOSTOP system based on analog radio signals at around 150 MHz. Transmitting a basic tone sequence will trigger any duly equipped trains receiving the signal to engage emergency braking. It’s implemented as part of the PKP radio system on the Polish railway network. Continue reading “Polish Railways Fall Victim To Cheap Radio Attack”

The State Of High Speed Rail, And A Look To Tomorrow

In the 21st century, the global transportation landscape is in shift. Politicians, engineers, and planners all want to move more people, more quickly, more cleanly. Amid the frenzy of innovative harebrained ideas, high-speed rail travel has surged to the forefront. It’s a quiet achiever, and a reliable solution for efficient, sustainable, and swift intercity and intercountry transit.

From the thriving economies of Europe and Asia to the burgeoning markets of the Middle East and America, high-speed rail networks are being planned, expanded, and upgraded whichever way you look. A combination of traditional and magnetic levitation (maglev) trains are being utilized, reaching speeds that were once the stuff of science fiction. As we set our sights towards the future, it’s worth taking a snapshot of the current state of high-speed rail, a field where technology, engineering brilliance, and visions of a greener tomorrow converge.
