Charlie Harley, #14153 Posted December 29, 2024 Posted December 29, 2024 Do the railroad companies periodically grind the top of rails with an angled pattern? Walking around the city and crossing tracks I have seen the marks in various degrees of covering the rails, including this one today. You can see the angled marks on the sides of the rails. In the middle it looks like they have just been worn off. Do they occasionally grind to improve traction? Curious minds want to know. Quote
Stump Water Posted December 29, 2024 Posted December 29, 2024 Yes. They grind the rails. Video 2 2 Quote
Marshal Mo Hare, SASS #45984 Posted December 29, 2024 Posted December 29, 2024 That deserves a follow-up with why railroads don’t need expansion joints. you won’t really need a slide rule. 1 2 Quote
Linn Keller, SASS 27332, BOLD 103 Posted December 29, 2024 Posted December 29, 2024 This one about expansion joints was interesting! Right after I got my nursing license -- I was still a working medic -- it was so blistering hot the rails expanded to the limit of their expansion joints. Blistering hot, middle of summer, chemical train coming up from the Ashland plant on the Ohio River, headed for Columbus: the hot rails bore against one another, crowded out of gauge, derailment. Hazmat derailment. We'd been taught the DuPont hazmat team was the best in the country. When I saw them at work I was convinced I'd been told truly! Ever since then I've wondered about welded rail ... thank you, Marshal, this is informative! 2 1 Quote
Marshal Mo Hare, SASS #45984 Posted December 29, 2024 Posted December 29, 2024 (edited) You’re very welcome. i can’t imagine doing a job where the best days for doing it are the hottest days of summer. Edited December 29, 2024 by Marshal Mo Hare, SASS #45984 3 Quote
Marshal Mo Hare, SASS #45984 Posted December 29, 2024 Posted December 29, 2024 The first video mention rail weights. I found this weight of railroad track can vary depending on the type and size of the rail. Common rail sizes include: Light rail (e.g., 60 lb/yd): Weighs about 30 lbs per foot. Standard rail (e.g., 132 lb/yd): Weighs about 66 lbs per foot. Heavy rail (e.g., 136 lb/yd): Weighs about 68 lbs per foot. Most modern freight railroads use heavier rails, typically ranging from 115 to 136 lbs per yard, translating to approximately 57 to 68 lbs per foot. The specific weight can vary based on design and material specifications, so it's always best to consult the manufacturer or a specific railroad for exact figures. Quote

Yes, rail is ground when the profile flattens or becomes worn abnormally. 3 hours ago, Marshal Mo Hare, SASS #45984 said: Light rail (e.g., 60 lb/yd): Weighs about 30 lbs per foot. The standard for Light Rail is 115 lb rail. It has been for decades. 60 lb rail is Trolley rail. 2 Quote

The math doesn't add up. 3 time the weight per foot is not even close to the weight per yard. Quote

On open track it’s usually the track that fails. Possibly due to pushing the limits of the trackwork itself. Occasionally it’s bad wheels - flanges too thin or too short. Sometimes it’s an erosion issue. Washed out roadbeds or erosion near grade crossings. In crossovers and yards most derailments are Operator / Engineer induced. 1 1 Quote

At switching yards monitors could be installed watching for them and signaling defects. as for trackwork, if there are warning signs, one car in a thousand or so could be equipped to look for them. as for operator/engineer, they have a union. its not unlike a cookie factory where hundreds of cookies pass every minute and defective ones get rejected.

That all sounds good in theory, but in reality projects like that cost billions, not millions due to the size and scope of the projects. 1 Quote

True, but it’s the human element that’s the problem. Bureaucrats, entrenched management imbeciles and closed minded union officers are the problem. 2 Quote
