43302 World Speed Record - HST passes Frinkley Lane (near Grantham) on 13 September 2019 with the 1B85 13:54 Newark North Gate to Kings Cross LNER service. This power car (as 43102) and 43159 hold the world speed record for diesel traction - 148 mph, achieved on 1 November 1987. Apparently, some drivers were convinced that 150 mph was easily possible, but BR banned any further record attempts. Not a lot of point when you've got the world record, I suppose!
