I heard they were testing it somewhere at the massive speed of 4 tenths of a mile in 8 hours, but the plan is to sink up to 30 piles (for catenary masts) per shift. This equals the usual length of one length of conductor wire about 1,200/500m. Although some press report 1.6km a night or take a total of 556 nights to do one track from London to Swansea
