![]() ![]() Roller bearings have a life of 100,000 miles to 300,000 miles and many things can cause them to overheat, such as fatigue cracking, water damage, mechanical damage, loose bearings or wheel defects. Homendy said the focus of the investigation will be the wheel set and the bearings. All the cars had placards, but the plastic placards melted in the fire. At least 20 hazmat cars were part of the train carrying lubricants, cooking oil, flammable gas and the vinyl chloride, with 17 cars fully loaded. The NTSB said it will look at how to protect important placards that help first responders know what’s inside a hazardous chemical car. The temperature in one of the five cars carrying vinyl chloride had started increasing to the point where explosion could occur. In talking about the controlled burn of rail cars containing vinyl chloride, Homendy stressed the NTSB had no part in that decision, but will evaluate whether the vent and burn followed established guidelines. During deceleration, the wheel bearing failed and car 23 derailed,” she said. “We have no evidence that the crew did anything wrong. ![]() There was also no evidence of track defect. She said no operational issue has been found with the wayside defect detectors, but they’re still looking at them. When the crew received the critical alarm for the 253-degree temperature, they started to slow and stop the train. In this case, the Norfolk Southern threshold for stopping and inspecting a car is 115 degrees. Homendy said the rail company sets the threshold for action regarding temperatures recorded by wayside detectors. At milepost 49.81, the suspect bearing’s temperature was 253 degrees Fahrenheit above ambient. At the next milepost 69.01, the temperature was 103 degrees Fahrenheit above ambient. The first at milepost 79.9 showed a temperature of 38 degrees Fahrenheit above the ambient temperature outside which was 10 degrees Fahrenheit at the time. The report goes into detail about temperatures of the wheel bearings measured by the wayside defect detectors along the way, with at least three detectors passed before the derailment. During this deceleration, an automatic emergency brake application initiated, and train 32N came to a stop.” The train engineer increased the dynamic brake application to further slow and stop the train. The wayside defect detector, or hot bearing detector (HBD), transmitted a critical audible alarm message instructing the crew to slow and stop the train to inspect a hot axle. In explaining the four-page preliminary report, which refers to the train as Train 32N, she said they have determined that car 23, a hopper car carrying plastic pellets, was the car that triggered the derailment and that “it was the combination of the hot axle and the plastic pellets that started the initial fire.”Īccording to the report, “Train 32N was operating with a dynamic brake application as the train passed a wayside defect detector on the east side of East Palestine, Ohio at milepost (MP) 49.81. With the shop, it’ll spread that work out.“Know that the NTSB has one goal and that is safety and ensuring that this never happens again,” she said. Volunteers used to furiously price things all summer getting ready for that one day, she said. The giant annual yard sales, which will continue, have typically filled the parking lot and brought in about $10,000 a year. It hosts AA meetings, Girl Scouts and a Lego club. The church, which she said is about 150 years old, has between 50 and 60 members. We’ve got a list going, if people are looking for something, we ask them to leave their name and number, and if something comes in, we’ll give them a call.” “Somebody came in looking for a pocketbook and we sold them a pocketbook. “We actually had someone come in who said, ‘My coffee pot broke this morning,’ Well, we’ve got one, and they walked out (with it,)” Davison said. They only thing they don’t accept is clothes, Davison said. All came in as new or gently used donations. There’s a double bed, lots of dishware, small appliances, books, toys and decorations. Prices range from 50 cents to several hundred dollars. We’ve had people coming in, since we’ve opened, every week bringing something.” “We kept some stuff that came in for the yard sale, that we thought would be nice to help get our shop open, and members of our congregation have been saving stuff inside. ![]()
