Secretary Pete is so unqualified for ANY government position it’s sad. But that’s what this administration is all about. Identity politics.
^^ sounds a likely cause.
this guy is well spoken and overall it is a decent video, he did include the cctv footage of (four) extremely over heated wheels, not a hot bearing. I’m skeptical the train crew would have put the train in emergency rather than make a normal stop as reported. I have never made other than a normal stop when a wayside detector reports a defect. One thing I take huge exception to that he said, is that it would take dozens of miles to stop this train. That is completely inaccurate, it would have taken about a train length and one half to stop with a service reduction normal stop, it would have stopped more quickly if placed in emergency. The data event recorder on the locomotives will record the type of air brake application used to stop the train. This train did not appear to be going very fast in the cctv footage, I would guess about 30 or so mph. This train would stop in less than it’s own length at that low speed with a service rate normal stop. Each car has brakes and is considered one operative brake, this train had 150 cars, so that’s 150 operative brakes. The total tonnage of the train divided by 150 gives the tons per operative brake. The TPOB didn’t seem all that high given the high number of cars. This guy really went into the weeds suggesting wheel bearing on freight cars are cleaned and repacked like on your Volkswagen in the driveway. Freight car wheel bearings are referred to as journals and are often produced by Timken but can be other manufacturers as well. Wheel bearings on freight cars are run to failure. You read that correctly, when they begin to run hot enough to set off a wayside detector they are replaced. The car would be set out at the nearest adjacent siding and the axel would be changed out at that location by a wheel truck and crew. Train crews are expected to report the axel size which is cast into the bearing cap of the hot journal to the train dispatcher so the correct axel is brought by the wheel truck crew. Modern freight car journals/bearings are grease packed roller bearings. They are pumped with additional grease if the car is being serviced at a facility and the stenciling on the car calls for it. They are never taken apart and cleaned. The entire axel is replaced by a new axel and wheel set to replace a failed journal. Otherwise this you tube guy did OK.here's anothe point of view who's the major stock holders in main street media and norfolk southern????
I totally agree with you with some of his maintenance issues.T

One strength of this video is the explanation he gives about the possible investor pressure to leave this underreported in the media. The engineer only operation you mention, was I believe a factor in the Quebec disaster I refer to in this thread. The short line RR that was involved in the Quebec event was an American company and that train started in the U.S. and terminated in Canada. The FRA granted this short line authorization to run with a single employee under a waiver. I ran trains from the States into Canada myself and laid over there. I was in Canada several time a week. This was my regular run until my retirement in 2017. Ironically the FRA has no jurisdiction in Canada. So this single employee operations must have been separately approved by Transport Canada. Speaking to hot journal detectors. In my experience they are frequently 20 or so miles apart and they have multiple functions these days like having a dragging equipment reporting feature also. These detectors report axel counts and occasionally count more axels than you think you have, meaning you have an orphan or extra car in your train, which is a really big deal to investigate Immediately especially if it’s placarded.I totally agree with you with some of his maintenance issues.
It's the media / NS not covering it is what I was presenting
With technology and telemetry today I dont understand why hot box or wheel sencers aren on every few miles of track or on each car.
ot comes down to money VS safety.
Just like the proposed 1 operator trains how is that suppose to work raise you hand and ask the boss if you can stop the train to take a dump?? " no just hold it till your next red signal" will be their replyor will the next generations of engines be operatable from the "throne"?
