I am chiming in mechanic. Its not just locomotives that I have cut up over my lifetime. I have cut up plastic molding machines, die cast machines, Huge stamping presses, locomotives and railcars, draglines, excavators, any piece of heavy equipment ever made, etc. The problem is always going to be you need to have bulk liquid oxygen and lots of it to cut through thick material I am busting through about a 1,000,000 cubic feet of oxygen in a month cutting right now. That is 222 of the liquid bottles that the majority of scrappers use in a month. Plus I am using about 2,000 gallons of propane every month and half to two months. We are also running jet torches. You want to buy one its 2500 for the torch. Each tip is 200 and tip nut is 50 bucks. You can't just walk into a welding store and buy one either. It took years of trial and error to figure out how to cut big big stuff. A h-scrapper number 8 tip can get it done but its going to be slow going. It also helps that I know one of the best cryogenic guys in the gas industry. He can build you a bulk trailer but the cost would be 60k plus depending upon what you want on it. Those are really your only two options. Spend a huge amount of cash or just do it with dewar tanks and a number 8 tip. I have seen where people have made crates for there liquid bottles and married six of them together. You can only get 1,000 cubic feet an hour out of a dewar tank. If you marry six of them together and have a 6,000 cubic feet and hour vaporizer you could run one jet torch off it. You would have to tie together three or four propane tanks to or you are just going to freeze the liquid propane to the bottom of the bottle and the liquid won't turn into gas. Making a pallet still doesn't make sense though because you aren't going to be getting a price break by doing it like that. It still involves a bunch of labor for the gas company. More labor more money. With a bulk tank the truck backs up hooks up dumps the product and rolls out. You also never run out of product because the tank is hooked up to a satellite which relays back how much product you have in the tank. When it gets below a certain amount they send out the truck and dump the product in your tank. No phone calls no hassle just a once a month bill. I hope this makes sense. If it doesn't ask questions I will try to answer them as best I can. The one thing I won't share is who or where I get my torches from since all my stuff is custom built. Victor and harris both make the torches they work good but in my opinion anything harris and victor is 100 percent JUNK in my opinion. I would suggest flametech if you are going to buy one.
