Colas 70807 not wasting any time tonight on the 688B Westbury to Liskeard 800ton rail train was running early and covered the 50 miles between Exeter St. Davids and Lipson Junction on the outskirts of Plymouth in 60 minutes. The video by Nick Campbell shows it motoring through Teignmouth station. The recent steam special with LMS 6201 Princess Elizabeth took 70 minutes for the same journey which gives an idea of  the power of the modern diesel freight locomotives and their ability to fit into the timetables with passenger trains.The Class 70’s are rated at 3700 horsepower.
