My sources tell me that the new BNSF braking system operates on Hot Air: the same substance powering this discussion thread..

[quote user="Murphy Siding"]
Wouldn't helium offer the same advantages as hydrogen in the braking systems, but be safer, considering that helium doesn't-you know- explode?
[/quote
Imagine the brakemen getting addicted to breathing the helium coming out of the brake line hoses and how they would sound. Soon transients would be doing it to. Listening to the RR scanner while they are switching will never be the same.
Wizlish Murphy Siding What they did, was simply turn the wheels around on the inner axles. Each car then has 4 axes. Starting from the front, the flanges go: innie, outtie, innie, outtie. A proper attempt at verisimilitude would be more consistent -- it would be innie, outie, outie, innie by your own description.

Not very much additional by way of additional track appliances might be necessary -- but weren't we warned to beware flange bearing frogs like Greeks bearing gifts? Which reminds me -- a fellow named Bucyrus has adapted a principle from, of all places, model railroading which is reminiscent of the resolution of the siege of Troy. I refer to the use of artificial-intelligence and servo technologies to create a large robotic hand, carried by a multirotor drone system, which can be lowered to stabilize a derailing train or remove derailed cars quickly from the path of opposing movements. I understand he is having some difficulty trademarking the phrase "Giant Hand Action" and will be asking for alternatives in the course of the next six hundred or so posts.

Ya missed it .. Warren B was at the amusement park, 6 Flags Under Nebrasky, and saw the local roller coaster hanging down from the rail. Picks up the phone, calls the NOC in Ft Worth and the rest is history.
And he gets all the pocket change that hits the ground.
When I saw "dual flange" I knew someone was pulleying my leg.
tree68 Hydrogen can be manufactured locally from anhydrous ammonia, using a retort. This means that with some minor modifications, locomotives would be able to generate their own hydrogen. USAF used to use just such equipment for filling weather balloons. (The date notwithstanding, that is true.)

Thers's the April Fool Joke. Hydrogen IS NOT PRODUCED BY ELECTROLYSIS!!! It is produced by reformation of natural gas and from catylitic cracking.
"Helium’s non-flammable nature makes it the only practical lifting gas for manned lighter-than-air flight, but it is scarce and expensive, and the use of helium can reduce a rigid airship’s payload by more than half."
http://www.airships.net/helium-hydrogen-airships
Helium is totally impractical as a locomotive fuel. Helium has far less lifting power to reduce the tare weight of railroad stock.
Electricty used to extract hydrogen may be generated using wind and solar energy. Hydrogen also burns extremely clean.
In case of an accident involving hydrogen, hydrogen burns completely. Ground water and water shed pollution is not at issue. The same may not be said for diesel, nor crude oil.
Another advantage for using hydrogen in the brake lines is that brake reductions will propagate faster than with air as the speed of sund in hydrogen is almost 4 tims faster than in air.
BNSF Testing Hydrogen Braking System
"The signs seem to be pointing towards the creation of a new generation of LNG-specific locomotives that would, in Thompson's words, "stop or substantially hold back the transition to hydrogen", but as hydrogen production continues to gather momentum and researchers find new ways to create hydrogen without emissions, the industry might look back on this as a short-sighted decision."
http://www.railway-technology.com/features/featurehydrogen-powered-rail-time-convert/
BNSF Railway today announced a further development as part of its ongoing committment using hydrogen to protect the environment.
A company spokesman said research into hydrogen as more than a fuel shows promising results. Hydrogen may make the railroad's braking systems greener. According to the spokesman, "Hydrogen weighs less than air. Using compressed hydrogen in place of air in our braking systems reduces the tare weight of rolling stock. This will allow us to carry more cargo on existing equipment and reduce our environomental impact."
Politicians and company officials inspected a locomotive and attached tank car. Compressed hydrogen from the tank supplies fuel for the locomotive and powers the train's brakes. All appeared impressed with what the saw.
Some have expressed concern about hydrogen's safety, especially where the railroad goes through populated areas. A mayor of a major midwestern city at the event was asked about hydrogen's safety, "Special permits for hydrogen trains passing through my city will be necessary. As long as permit fees cover city budget shortfalls, hydrogen powered trains present no great concerns."
Next stop Lakehurst, NJ? Time will tell what the future holds for hydrogen's use on America's Railroads.
carnej1 I am not surprised as BNSF has long been at the forefront of technological progress. The same holds true of it's predecessor railroads;Why just today I read that, back in the early 20th Century the Great Northern and the ATSF were the first major railroads in the world to issue all fireman with Left Handed Smoke Shifters, which made their jobs much easier..

Murphy Siding The local putt-putt train through town- the Ellis & Eastern- all 4 miles of it, has already figured this out. They haul rock from a quarry on the west side of town to an asphalt plant on the east side of town. Because of track quality through the center of town on old CNW track, they had problems in the past. What they did, was simply turn the wheels around on the inner axles. Each car then has 4 axes. Starting from the front, the flanges go: innie, outtie, innie, outtie. They don't operate at high speeds, and since they have virtually no steep grades, big turns, or many switches, I don't know if their application would work on a big railroad.**Without spellcheck, I can't tell if I spelled innie and outtie correctly. I may have to go on www.belly-buttonidentification.com to research that a bit.

Somehow, I think we are being" HAD"...
What with this being April 1st? The Date reserved for celebrating of Strange, Weird, Stuff usually reserved for April Fools....
Actually what the BNSF intends to do is install the outside flanges before going through larger metropolitan areas at 35 mph, and then remove them again at the outskirts of the city. Sort of like winter chains on tires.
If you want to see a bewildering photo, take a look at page 12 of J.B. Snell's classic book "Early Railways," showing the double flange track work at the Oakley (U.K.) quarries, Blaenau Festiniog. As Snell writes "its intricacy shows why this system never became popular."
Best regards of the day to you.

WizlishThere is apparently a parallel research effort in flange lubrication, using biodegradable and metatribological oleum serpente spp. derived from biorenewable sources. Remarkable economies over traditional methods are anticipated.
Oleum serpente spp., indeed! Very good. Happy April Fools Day!

We have a painting in the offices of the Jackson Street Roundhouse where the flanges are on the outside of the rail for a logging railroad. Apparently the artist was good at trees but never looked at the train's wheels. So perhaps BNSF's idea has merit.
What day is it?
