  2. 2. TALGO (Tren Articulado Ligero Goicoech ea Oriol, Goicoechea-Oriol light articulated train), Alejandro Goicoechea and José Luis Oriol being the founders of the company. Talgo Patents S.A. was first incorporated in 1942. In March 2007 Talgo sold its Finnish rolling stock manufacturing subsidiary Talgo Oy to its local management and other Finnish investors. The company, which Talgo had owned for only seven years, reverted to its previous name of Transtech Oy. The company spends 10 INTRODUCTION

The IPO valued the company at €1.27 billion.[4] In July 2015, Talgo stated its intention to ship a Series 9 train to India at its own cost as a demonstration on the Mumbai- Delhi rail route.
  4. 4. Talgo trains are best known for their unconventional articulated railway passenger car that uses a type similar to the Jacobs bogie that Talgo patented in 1941, similar to the Robert Stephenson and Company trains.. The wheels are mounted in pairs but not joined by an axleand the bogies are shared between coaches rather than underneath individual coaches. This allows a railway car to take a turn at higher speed with less swaying. As the coaches are not mounted directly onto wheel bogies, the coaches are more easily insulated from track noise. Talgo trains fitted with variable gauge DESIGN

Since the introduction of the Talgo Pendular in 1980, the train tilts naturally inwards on curves, allowing it to run faster on curves without causing discomfort to passengers. The carriage tilting system pivots around the top of the suspension columns, which has the effect of partially cancelling out the effects of the lateral acceleration when cornering.
  6. 6. Here's all you need to know about the Talgo trains that we are about to welcome on our railway tracks: 1. A Talgo 250 can run at the speed of 250 kmph. However, trials in India will only be conducted at 150- 160 kmph.
  7. 7. 2. Its lighter trains can cut travel time by 30 per cent. In fact, Talgo trains are expected to cover the Mumbai-Delhi stretch by 12 hours, unlike the Rajdhani which takes 17 hours.
  8. 8. 3. Talgo train coaches would save up to Rs 1 crore as compared to the LHB coaches used in Rajdhani and Shatabdi trains. They are also said to require "less maintainance".
  9. 9. 4. Unlike that for Japanese bullet trains, no major overhauling of tracks is said to be required for running Talgo trains in India.
  10. 10. 5. Amenities like footrests, reading lights, tables, audio entertainment control, etc. are provided for every individual seat. The trains also come with monitors for video entertainment.
  11. 11. 6. Talgo trains have the technology to keep interiors pleasant even when the temperature outside crosses 50 degree Celsius or drops below -20 degree Celsius.
  12. 12. 7. Talgo's official website also promises showe units, in-house restaurant and a cafeteria car for pasenger coaches.
  13. 13. 8. Talgo trains' can also reduce Railways' energy bill by 30 per cent, as its "reduced weight and inalterability against atmospheric agents is translated into lower energy consumption"
  14. 14. 9. Talgo 250 was the first high speed train to run in Central Asia. In Uzbekistan, it runs on a daily basis
  15. 15. 10. Pretty and efficient, yes, but these fancy Talgo trains will make train travel more expensive than it is now.
  16. 16. The progress of the Spanish rail company Talgo conducting trial runs of its trains in existing Indian tracks : The trials recently conducted on Delhi Mathura stretch have reported to touch a maximum speed of 180 kmph. From 1 August trials are planned to be done on Delhi-Kota- Vadodara-Mumbai track and the distance is planned to be covered in almost 12 hours. Talgo coaches are comparatively low in height as that of conventional coaches,thus are more stable at higher speeds and are having tilt mechanism to have great speed even on the curves,which predominantly exist in IR tracks.
  17. 17. The Spanish-made high speed trains, Talgo, will soon be pressed into service but only after modifications to set them operational for Indian platforms, UPDATED ON 2–8–2016 16:00 HRS Talgo’s nine-coach train, pulled by an Indian Railways engine, departed from New Delhi at 19:55 hours on Monday. Talgo’s train, owing to heavy rains enroute and point failure at Mathura Junction, reached at 11:36 AM at Mumbai Central. Rajdhani Express takes 15 hours and 50 minutes to traverse the distance between New Delhi and Mumbai Central. If Talgo’s trial had gone as per schedule and without any glitches, the train would have taken 12 hours 47 minutes for the journey, that is approximately 3 hours less than Rajdhani.
  18. 18. Railways to start trial of Talgo trains on Delhi-Mumbai section from August One 2016
  19. 19. NEW DELHI: Indian Railways will start the trials of Spanish-made Talgo trains on the busiest Delhi-Mumbai section from August 1 after its successful trials on Mathura-Palwal, where it achieved 180 kmph with fully loaded capacity Thursday. The trials on Delhi-Mumbai section will be done at a maximum speed of 150 kmph for nearly a month before a report is submitted to Railway Board. At present Delhi-Mumbai Rajdhani runs at an average speed of 80 kmph covering 1388 km distance between the two cities in 16 hours. Talgo coaches can cut the journey time between Delhi and Mumbai by 4 hours 30 minutes. “The primary results so far are similar to as claimed by the company and we will make a detailed report on other technicalities. Next week we will conduct trials of emergency braking distance system which means
  20. 20. distance it takes to stop after applying emergency break at 160 kmph,” said a senior railway officer monitoring the trials. With Railways working to increase speed of trains, Talgo trains can be a game changer if they succeed in achieving claimed targets of running on existing rails at 180 kmph without any major infrastructure changes. At present, Gatimaan Express is the fastest train at 160 km/hr. The cost of a Talgo coach is Rs 5 crore and it requires minimal infrastructure upgrade to run on Indian rails. Talgo envisages the journey between Delhi and Mumbai can be completed in about 11 hour 40 minutes as compared to 16 hours 10 minutes at present. The Talgo coaches can run on curved rails without decelerating speed. Besides reducing travel time, Talgo's lighter trains consume 30 percent less energy. The Railways has set up a Mobility Directorate to work on strategies to increase speed of
  21. 21. trains. Gatimaan Express – India's first semi-high speed that clocks 160 kmph, was launched on the Delhi-Agra route in April.

  27. 27. •TALGO's RD System, used to change automatically the distance between the wheels of the axles, has been successfully used since 1968 in variable-gauge axles of Talgo's trains. •The TALGO RD System permits the automatic change of the distance between the wheels of the railway vehicles in order to make possible the running on different gauge tracks. • The TALGO RD system can be applied to different models of passenger coaches, power heads, locomotives and freight wagons with full security and reliability, through standard /Spanish and Russian / standard gauge Railway networks. • The change is made without human intervention while the train is running at low speed (15 Km/h) through a special installation fixed on the track in betweenthe tracks of different gauges. • This is a unique and simple system based on the elevation of the suspension above the Centre of Gravity of the carbodies. This system is used to reduce the lateral forces that affect passengerswhen traveling on curves. • The carbodies act under the effect of natural ( centrifugal ) forces without any loss of safety and comfort levels, thanks to the steered wheels and the unique talgo wheelset assembly characteristics... … carbodies tilt towards the interior of the curves in direct relationship to the travelling velocity... … reducing the values of lateral forces that act uponthe passengers... … thereby enabling a 25% increase in travel speed when traveling on a curve, provided that the tracks' resistance characteristics are appropriate. ... reducing the levels of the wheel-rail interactions allowing to increase speeds in curves without affecting safety.
