<p>Air Brakes are big dumb brutes who get nothing passed on to the shoes, a little bit of reduction passed on OR ALL OF IT BIG HOLE.</p><p>The Airbrake system on a train cannot "Pick" one axle to put a brake on. If it could, it is not agile enough to keep up. Even if it could, the engine will be exhausted trying to feed all of those little demanding air brakes working individually. No. Airbrakes are a all for one and one for all within the limits of the piping.</p><p>Electronic braking on cars can be put onto trains, trucks or anything else but I consider them rather a bit of a ...**searches for word... blashemy. Sometimes you just gotta jog a wheel or a pair loose to get your vehicle where you want it to. You can load down a car with all the fancy frankenbraking driven by the very best in nanny controls but it cannot ever make up for very bad drivers.</p><p>Now, ABS (Anti Locking Braking) will have potential for saving flat spots on steel wheels if you could build one stout and big enough to withstand railroad duty with zero maintaince. Ive used this on big trucks over the years and let's just say there are at least a dozen lives including my own saved time after time by this wonderful system.</p><p>Having thought on this slack issue, I wonder if the UK has snuck one over on us enjoying thier buffers in addition to thier couplers.</p>
