Rail welding

Thermite welding is used to join rails together in the field. Everything comes in a kit, with packing up around the joint, then the crucible or pot put above the joint, and lit up. Molten metal flows out the bottom, which is left to cool. The packing is removed, and then the joint is ground smooth.
