Indeed.

Somebody posted that the engineer shouldn’t have pulled the brake before the curve. Does anyone know why?

Same concept as with a car under lateral g-force in a turn - rolling wheels are more stable and likely to keep you upright and on track. Brake before you reach the hazard and let off just prior to entering it.

Considering that activist homosexuals are largely responsible for the deaths of thousands of innocent people through proliferating AIDS, and unapologetically so, it surprises me not one bit that this homo may have had no qualms about taking all these passengers with him on his suicide mission.

I’m afraid that if any of this had anything to do with his “gayness,” the info will be deep-sixed in the interest of “gay rights.”

How are you even sure that fitness standards are the same for everyone? Also, there’s the real question of whether or not the person had good motives to end his life, like fatal disease, or going broke, etc.

“In barely a minute, its speed jumped from 70 m.p.h. to 102 m.p.h.”

Is that even possible?

Pretty much.

Hella acceleration for a heavy train...

Absent a Germanwings scenario it sounds like Toyota needs to recall again

several questions: what was his THC, alcohol and cocaine levels?

That brings up a very interesting question. If recreational marijuana use is legalized in more and more jurisdictions, will there be any legal force to banning it for operators of public transportation equipment? Are train engineers banned from ever drinking alcohol? Could they be? There is an insane political philosophy that has developed that says what is "legal" is a right, such as homosexuality or "changing your sex." Why would marijuana be any different?

Regardless,

the crash was caused by Republicans refusing to invest in infrastructure.

What in the rails allowed the engineer to gun the acceleration so much?

Begin countdown to “nothing to see here” response from NTSB.

The train was homophobic.

Time for a Mimosa Summit.

That’s why I was curious if the grade was flat or?? Only pulling six cars.. That locomotive probably had plenty of ooomph

Yep, he sped the train up at the precise time he needed to get it 100 at the curve entrance knowing it would derail.

He’s the firefighter who sets fires.

That sounds logical.

The FRA is pushing for ECP equipped tank cars for hauling oil, or restricting unit trains hauling oil to 30mph. We're barely keeping up with the PTC installs as it is, and the feds aren't budging on the deadline for January. As far as ECP goes, how does it compare to using a HOT/EOT system, or similar DPU setup? I could see an even brakepipe reduction across all of the cars helping a train stop faster, but will it help with preventing derails due to shoving and bunching?

Regardless, I would like to see the downloads from the event recorder and TIR for the locomotive. You can't fudge that data. I still think this either operator error, or deliberate.

The HOT/EOT device just ensure integrity of the airpipe. ECP allows braking to initiate from the rear. Tension from the rear instead of increasing compression from the front to rear. Fewer wheel lockups with resulting flat spots. Tests in the mid-2000's yielded 35% faster stops.

My colleague spent a week in Pueblo, CO with a 48 KHz digital audio recorder connected to many identified defects on the "hospital train". They were cataloged, then characterized using DSP techniques. The bearing cone, cage, cup and roller frequencies can be extracted based on geometry and angular velocity. I turned his MATLAB work into real time monitoring with analysis and data reduction before saving to a web based database for trend analysis.

The bearing burn-off between hot bearing detectors in the rail bed was handled using sensors in the "stink bomb" holes on the bearing adapters. I can send the exact axle, side and car id to the locomotive engineer in real time...before a bearing burns off and derails the car. Inner and outer bearing adapter temperature measurements can expose wear requiring service ahead of a catastrophic failure. On a train that isn't in motion, I can discern which side of the train is illuminated by sunlight as the bearings are warmer than the shadowed side. Fun details gleaned from field testing.

I agree. We need to see the event recorder logs. All the yapping about the windshield being hit by a projectile appears to be intended to distract attention from the engineer's responsibility to actively control the speed.
