Talgo tilting train- between Mysore Bangalore

  • Travel time between Bengaluru and Mysuru could be reduced to 90 minutes in the near future if trials with a high speed, tilting train manufactured by Spanish manufacturer Talgo conducted between Delhi and Mumbai in the next few days are successful.

  • Larger orders for the trains will be placed based upon the success of the trial run, which will likely begin from August 1DC283_hokuto_001
  • The train recently clocked 180 kmph this week between Mathura and Palwal during a trial run.
  • This technology will be cheaper as it can run on existing tracks. Since there are a lot of curves on the Bengaluru-Mysuru line, it will be better
  • The state government had proposed the use of these trains on the route to reduce the travel time without having to create new infrastructure.
  • Track doubling and electrification work on the line is almost completed. A major hurdle of shifting Tipu Sultan’s armoury taken up by US based company Wolfe Private Limited will also be completed soon.
  • In all probability, the project will be completed by year-end and tilting train coaches will be an added attraction on the track

About Talgo tilting train

  • Tilting train coaches are product of Talgo-the Spanish manufacturer of intercity, standard, and high speed trains.
  • These coaches are light in weight and designed in a way that it can run on curves without decelerating.
  • The Indian Railway recently conducted the first trial run in the stretch between Bareilly and Moradabad, as part of strategy to increase the speed of the trains
  • A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train (or other vehicle) rounds a curve at speed, objects inside the train experience inertia. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest due to its centripetal force, and standing passengers to lose their balance. Tilting trains are designed to counteract this discomfort. In a curve to the left, the train tilts to the left to compensate for the g-force push to the right, and vice versa. The train may be constructed such that inertial forces cause the tilting (passive tilt), or it may have a computer-controlled power mechanism (active tilt).
  • Besides making travel faster, the technology also makes train movement on curves smoother, making journeys more comfortable for passengers.
  • At present, trains turn with a jerk at curves. Moreover, drivers reduce speed at curves and bends for smooth and safe operation. The new technology prevents derailment at curves even at high speeds. This reduces travel time and improves punctuality. During the trial, RDSO will use test speeds as low as 80kmph to as high as 180kmph.
  • Talgo rakes have a make-up markedly different from Indian rakes. Indian railways has individual coaches mounted on separate bogies (portion with axles and wheels). Every bogey has eight wheels which are connected through an axle but coaches are not inter-connected. This makes a train tilt outwards at curves and often with a jerk. The new technology, on the contrary, is based on ‘natural’ tilting system and has coaches connected at the vestibule.
  • At every coach-junction, there are two sets of wheels and bogies are shared between coaches. This inter-connects coaches and the train tilts inwards while turning at the curve.
  • It is projected to cut running time by 25% which will also reduce railways energy bills.
