Naw, it wasn't thermite welding. I think the machine was a flash-butt welder because it got hooked up to some really big electrical and it milled the weld afterward all in one quick operation. IIRC the company was Holland & Co 'cos the guys running the machine all spoke with a strong Midwest/Chicago accent. If you click on the transit system link there's a picture of the machine we lifted up to weld the crane rail on this job I was on.
