18/1/86 - Preston, LMR

Collision involving Class 104 / Class 86

Info from Bill Read

Collision of Class 104 power-twin and stationary Loco 47 111. M53482-M53433. 44 passengers required hospital treatment (the driver and many passengers had retired to the rear car). The conclusion was that the driver’s brake valve had been inadvertently placed in the “lap” position resulting in the train brake pipe and “topside” vacuum being gradually destroyed during the journey from Carlisle. The driver may have been distracted by the presence of passengers of the football-supporters charter being in the cab. M53482 was severely damaged.
