Record Breaker 43102 - Darlington - 31 Oct 1987
HST power car 43102 with the SIG bogie test train at Darlington, 31 October 1987.
Formation was - 43102 + 44090 + 42317 + 12140 + 44101 + 43159.
The following day, 1st November 1987 saw test running between York and Darlington, taking speed up in 5 mile/h steps above 125 mile/h to confirm the stability up to 145 mile/h. In fact during one run the speed attained was slightly higher, and we achieved what became a diesel speed record of 148 mile/h over a measured mile on a southbound run between Darlington and York, with an absolute maximum recorded of 148.5 mile/h just south of Northallerton.
HST World Diesel Speed Record Train.
