Bus record

A methane-powered bus has set a speed record of nearly 124km/h at a test track in the UK. The bus, from the southern city of Reading, was converted to run on compressed methane from cow manure and was painted black and white like a Friesian cow. Mechanics removed the bus’s engine governor that restricted the vehicle’s speed to 90km/h. The bus then broke the record on the banked high-speed circuit at Millbrook Proving Ground, near the city of Bedford. The cow waste was broken down by anaerobic digestion to p

A methane-powered bus has set a speed record of nearly 124km/h at a test track in the UK. The bus, from the southern city of Reading, was converted to run on compressed methane from cow manure and was painted black and white like a Friesian cow. Mechanics removed the bus’s engine governor that restricted the vehicle’s speed to 90km/h. The bus then broke the record on the banked high-speed circuit at Millbrook Proving Ground, near the city of Bedford. The cow waste was broken down by anaerobic digestion to produce biogas, which was then liquefied and stored in several fuel tanks within the expanded roof of the bus. The bus’s speed would not be a Guinness World Record because it failed to exceed 241km/h. But the vehicle did make an appealing sound as it swept past on the track.

    Manufacturers are constantly upgrading marking materials and equipment. Now those responsible for highways are being asked to do more as Patrick Smith reports. A recent report claimed that nearly one-third of the length of Britain's single carriageway A-roads have white lines so worn out that they do not meet recognised standards. According to the LifeLines Report, an assessment of more than 2,400km of the road network, Britain's most dangerous roads have the most worn-out centre line markings of all, leavi

    Innovative roadmarking technologies will increase productivity, improve conspicuity in poor conditions and offer increased wear life - Mike Woof writes. Major advances have been seen in roadmarking systems now being offered on the market. More sophisticated machinery will increase productivity and quality when installing markings, while new systems will also last longer in use. In addition, smart technologies can detect wear and provide highway authorities with an accurate picture of network safety, at comp
