All tamping so far has been done on track which is either connected to or replacing existing rail lines, so moving the tamping and blasting equipment to the location of the track has been easy. Here, the track is isolated - separated from the main railway line it eventually connects to by embedded track, with three very tight radii turns. The Harsco Mark IV tamper surely can't navigate those curves (it has fixed axles on a very long frame), so I'm quite curious how they plan on doing maintenance on this section of track in the long term.
There has to be some way to get the tamper to the ballasted track - I'm guessing some kind of custom truck trailer that can be aligned with the rail, and roll it on and off.
