Saw a group of the 09-16 Dyna cats cross the rails yesterday. Weirdest yet coolest looking rail machinery I've ever seen. Had to look em up and see what they are and do. Needless to say, mind blown. -Jett
First time I see a Plasser with double tamping tools inside and single outside, also surfaces very slowly for a high production machine, I operated many different types for years.
This area of farm crossing got a total lift of 150mm from the level we laid and this machine wouldn't allow that much. Completed in 3 passes though. Computer very definitely said no!
If height clearance isn't an issue, then you'd go back and lift to the new level. Tunnels and bridges,etc would mean cutting out ballast to lower the track again. The pre-tamping recording pass of the machine over the worksite determines levels and computer does the rest.
I wonder if you can help me? Do Tamping machine's have lasers on them and if they do, do they point upwards towards the sky and what colour are the laser beams on them?
@@Umbrey_Dunctum I found out on another channel that they dont point up to the sky only point towards the track. As I got told there is no reason to point them to the sky. I hope that helps.
Many years ago, I worked in a building that backed up to a RR spur in a business district. I could look up and down the track behind our building and see that track was an _absolute mess_ both horizontally AND vertically! It was amazing (and kind of scary) to see how much a locomotive and cars would wiggle and move around when coming up the track! Anyway... One day a machine similar to the one in this video came along and worked on the track. As luck would have it, the crew stopped for lunch right behind our building so they could sit on the lawn under a tree and eat! That gave me a perfect opportunity to run out there and ask 'em a bunch of questions about the equipment they were using. One of the questions I had for them was, how does the tamper **know** how much to lift/shift the track? What I was told was that they setup a laser much further down the track ahead of the tamper. The laser beam is directed _back_ at the tamper, and the tamper then uses sensors and a computer to calculate exactly how much to lift/move the track to maintain itself on the beam. For what it's worth, I went out there the next day and the track looked absolutely perfect!!! Another crew came along within the next day or so and added more gravel, and the next time I watched a train come through, it had NO side-to-side, up-and-down, or swaying movement at all!!!

Plus I like the equipment that redistributes the gravel
here bcos i just discovered what this machine is because i got woken up by it at 2:30 am ! x

A tamping machine is working right next to my house as I type 😭
It's 2am, one of these has just woke me up.
Wondered what the fack was going on!
Cool video Brent thanks for posting
Useful being able to move the lifting assembly to clear fishplates and fastenings, compared with fixed 07.
Interesting’ you can really see that the track is a few cm higher after the tampering

Computer very definitely said no!
Blast efficiency
Nice
So cool whoever invented this. How often do they tamp it? And how do the keep vegetation from growing around the tracks?
The track gets a maintenence tamp once a year. Ballast is sprayed with a total herbicide annually to keep the stone clean and weed free.
Can Tamper reserve?
What happens if you lift too much, pushing the sleepers down again is surely not such an easy task?

Lol ...that’s what I came to find out too, after seeing a vid on the Wales incident and Amsterdam UFO video.

Do they use these machines at night?
99% of all the work that on-track machines like this do is at night.
@@brentncleeton9771 Thanks for that.
Me gustaría hablar con alguien que haya trabajado en una tamper 3000
But good job
Packing machine
Anyone who thinks these machines are cool, has never been woken up by one in the middle of the night.😵
rails should NEVER be tampered with ..its a criminal offence .
