A couple of years ago they re did the track that runs outside our place as well. Was an interesting week or so while they did it.
About 14 years ago was a BNSF conductor on a ballast train. It was put down by a string of hoppers 1 car at a time by the track gang foreman.
Watched a switch being replaced a couple years ago. They brought in a flat car with parts and a crane. The parts where layed out beside the tracks and assembled on the first day. On the second day they removed the old switch, level the bed, using two cranes they picked up the assembled new switch and placed it where the old one was. It was not unlike what we do to replace a switch on a layout but, in a much larger scale.
