Railway Track Tamping. How, Why and When It Is Done on the Track

[@marclattoni1959]

Thanks for a clear and not overly detailed explanation.

Glad you found it useful!

Spent many a day on the kango, packing ballast on routine maintenance and after working on a procession at night. And while working at one P'way, they needed a site warden on a tamper. That was the easiest two weeks I've had, as they told me to get my head down (easier said than done with the motion of the tamper once she got going) or help myself to a coffee. I was going to mention, the tamper I worked on, when she got to the site, she would make a recording run and then do the tamping run. When we worked on a weekend relay, we would remove some ballast from the sleeper top, so the operator of the tamper could see their location.

Pretty much spot on, just one thing you came close to but didn't mention. The frequency of the vibration of the tines also causes the ballast to act as if it were a fluid. This enables it to flow in to voids beneath the sleeper beyond where the tines could just push it.

I did read that somewhere! I tried to work out a way to state it without it sound far fetched! You have stated it very clearly so thank you!

[@aimdrummer]

@thepwayengineer I can't remember where I read it now, could have been in one of the PWI books.

[@thepwayengineer]

@@aimdrummer Probably the same one I read!

Glad you enjoyed it

A big thumbs up from me in recognition of the clarity of explanation in all your videos and for the consistently top-notch presentation. Add in the animations prevalent throughout this video and my mind is left boggling at the sheer amount of effort and time that goes in to each and every PWay Engineer video. Thank you!

[@thepwayengineer]

Thank you, that is very very kind of you!

Great Video! I am nit-picking but for your information ALC stands for Automatischer Leit Computer. I've heard many variations using lifting/lining and yours is good too, however, when translated from German it means automatic guiding computer (AGC) as it is needed to guide the machine in transitions and curves. Sorry to be a nerd! 🙂

[@thepwayengineer]

Thank you very much for the correction!

[@PRISMS_Music]

Great video ! I’d be curious to see a video on ballastless track found in china and see how it holds up to ballast

[@thepwayengineer]

I have a video that might give you a starting point! Check it out here: kzbin.info/www/bejne/jYKpg4yJopWWfMk

I like counting dropped joints.
