Please subscribe!! Having only seen a demonstaration of this at an open day in the UK, I was pleased to see this happening on the main line in the US. The defective weld had been marked, once the P-way team arrived there was one last train before the repair began, the defective weld was cut out quickly leaving a 2 to 3 inch gap, the ends where then aligned and the mould fitted. As soon as the track ends were pre-heated the Thermite was ignited and the gap filled. There was then much cutting, bashing and grinding before the joint was finished. The next train passed over the weld within two hours of the previous train.
