Tell Randy he is correct. The rail road is next to where I work,and they was doing this exact thing this week. It makes alot of noise while they are doing it. And when they come back through taking up the excess rock it is a car of some kind with 2 big wheels that look like water wheels ( a big wheel with buckets near a stream) and they scoop up the rock and it goes to a belt that throws it into a car behind it...pretty neat to watch while your working

It is hard to tell from the photo, and I'm not all that familiar with AMTRAK equipment since the government gets newer and better stuff than us private guys but it appears that this is an undercutter. What this machine does is lift the rail and ties and "wakes up" the ballast and substructure underneath. As you can imagine, with all that weight cruising on top tends to pack things fairly tight. This machine will disturb, or undercut, the ballast underneath causing the ballast to unpack which will improve drainage. Drainage on a main line is a railroad's worst enemy.
I hope this answers your question, and if I'm wrong, somebody please jump in!
So if Randy is still around I have a few things to say:
1: You're a lucky dude. If you don't know why look at the woman next to you. Then slap yourself up-side the head for not knowing why you're so lucky.
2: When are you gonna trade that Nissan in on a PowerStroke?
Well, I'm flattered. He smacked himself on the head and just smiled.
He said he'd buy a Powerstroke if you start the "Buy Randy a Powerstroke" fund.

I guess every railroad has undercutters of their own, I've been looking at them online and they all look a bit different.
there was an episode of Extreme Trains, or Modern Marvels, that I watched a week or so ago that showed one in action close up. It also showed the tie replacer. It moves to a spot , reaches down with spike pullers, and then throws the old tie out to the side, and then it slides a new one into the the same place and spikes it.
Shall I assume he was a Darwin award winner that year?
I don't know much about the circumstances there. I saw it on some other forums I use and I knew it was a good
picture of the actual bucket wheel.
One other thing they can do with those bucket wheels is use them to mine what they are actually going for.
Ie: If they're mining coal they can have the bucket wheel dig out a bunch of coal.
They sometimes put massive conveyors attached to them and the material goes from the bucket to a conveyor
to the long conveyor over to whatever facility they are sending the material to. No trucks necessary.
