That first bolted rail joint you show looks like an insulated joint. That spacer material between the rails keeps them electrically isolated. You have a number of switches there and signaling around crossovers like that can get pretty complicated.

Dave at *ccrx 6700* showed a video a year ago where they weld rail with thermite and leave the broken crucible material and welding slag behind after they knock the welds clean with a hammer, before grinding and finishing the weld.

thermite welding, you can see quite a few examples on youtube... and there was one I watched a few years ago where they showed the entire process of track removal, laying new track and thermite welding parts into place

Bro needs to watch how they weld... They didn't weld with sticks... It's literally thermite weld.

Ah really? If I get another opportunity to see them do the work I will ask to do a video of them. Did you use to or do you weld tracks?
