Thanks, Chuck. I had watched a couple of thermite welds on streetcar tracks about 25 years ago, and it's always fascinating -- and blinding.

I hope they clip this out to save, but the Tehachapi Depot Museum railcam today has an excellent "up close and personal" sequence starting about 9:00 am with a UP crew making two thermite welds at the Green Street crossing project. Amazing stuff, especially the post-weld work getting the rail profile back in shape. A lot of innovation in making the whole process efficient.
