Trestrol vehicle (Lab 24) fitted with APT experimental H2X power bogies - Lateral H-force data on curved and straight track for Beattock high speed tests carried out on the 27th March 1977 (TM-DOS-58)

Running tests with Trestrol at Beattock were successfully carried out up to speeds of 200 km/h and 6° cant deficiency. Lateral H-forces did not exceed 0.85 (10+ P/3) for curved or straight track. The measured peak H force of 46 KN at Beattock bas been exceeded elsewhere on the West...
