OK...cool picture...but I need further explaination on this one...

When rail joints separate, ES crews light fires along the web of the rail to heat it and cause it to expand so the joint can be repaired. I usually see them use a length of rope soaked in diesel fuel.

Here is some further information! When it gets cold, the rail shrinks and actually snaps bolts at joints which isn't good. In this case, it shrank so much that we couldn't get the bolts back in without heating the rail up, which makes it expand back into place. We spread a slurry mixture of diesel fuel and ground newspaper along the rail, light it, wait for it heat up, "coax" it a little bit by pounding on it, then place new bolts and anchors on the track. If it all works as planned you don't have to worry about it happening again!

Very interesting procedure caught on camera. Had not heard of this method before, but it for sure looks impressive.
