TECHNOLOGY : EPISODE 12 BRITISH TRAINS PLANS TO POWERED BY HUMAN WASTE & DISCARDED FOOD

Image
  Britain’s  Trains powered by human waste and discarded food could be introduced to its network under plans to phase out dirty diesel engines. The 'Bio Ultra' railcar is the brainchild of a team of engineers led by the Worcester-based Ultra Light Rail Partners and will be able to carry up to 120 passengers. With a top speed of 50 mph, the 66 feet (20m) long car will turn biomethane gas into electrical power which will charge the train's batteries and drive its motors. The development is being support by a £60,000 grant from Innovate UK, the Government's non-departmental research-funding agency. This is the second such grant that the team have been awarded. The previous, for £350,000, was used to build a smaller, 60-person railcar earlier this year. This demo 'mini train' which was around 33 feet (10m) long and weighed some 12 tonnes was put through its paces at Motorail’s Long Marston test facility in July 2020. In the wake of COVID-19, however, the new...

ENGINEERING LESSONS : EPISODE 17 DELHI METRO DRIVERLESS TRAIN CRASHES INTO WALL

  Driverless Train of Delhi Metro's Magenta Line crashes into wall Incident date: Dec 2017 Location:  Delhi Metro's Magenta line, Kalindi Kunj Metro Station. Fatality  : No Driverless train of Delhi Metro's Magenta line crashed into a wall of Kalindi Kunj metro station. The Kalkaji -Botanical Garden metro line,  the incident happened within the gated boundary of the station.  Delhi Metro's new generation trains that can be maneuvered without drivers are going to run on this route. Movement of these driverless trains would be facilitated by advanced Communication Based Train Control (CBTC) signaling technology. Initially it is planned to operated by drivers for the initial couple of years. 12.64 km Magenta line was given the necessary safety approvals by Commissioner for Metro Rail Safety (CMRS). A trial train was moved from the workshop without testing the brake system as a result of which, while the train was moving up the ramp for washing, it ro...

ENGINEERING LESSONS : EPISODE 18 WHALE CATCHES DUTCH METRO TRAIN BEFORE CRASHING IN WATER

WHALE CATCHES DUTCH METRO TRAIN AFTER DEADLY CRASH  Date of the Incident:  2 November 2020 Place :  De Akkers station in Spijkenisse, Netherlands Metro train in Spijkenisse, near the city of Rotterdam, Netherlands crashed through a barrier at the end of the tracks. Instead of plummeting into the water below, the train was caught by a sculpture of a whale's tail.  Several meters above the ground, the train was left perched upon one of two tail fins. The sculpture was built around 20 years ago in a park underneath the raised metro  by artist Maarten Struijs , its name a deliberate play on the fact that it is a “tail track” at the end of the line. Experts said it was unclear why the train had not been stopped by automatic buffers at the end of the track. Apparently something went wrong technically, possibly combined with human error. Surprisingly the sculpture built of plastic have saved the train from falling down, even after 20 years the sculpture made of pl...
