Talgo Train in India attained 150 kmph

Talgo’s train has finally completed its Delhi to Mumbai run in 12 hours 36 minutes (not accounting for delay), beating Rajdhani Express, which takes around 15 hours and 50 minutes. The train departed from Delhi on Friday afternoon and reached Mumbai on time in the early hours of Saturday morning, despite heavy rainfall on the Surat to Mumbai stretch. Vijay Kumar, Executive Director, Infrastructure at Railway Board, who was in the train during this run said, “The train’s trial was successful despite heavy rainfall. We were delayed by around 18 minutes on account of unusual occurrences, which increased the total journey time a bit, but that had nothing to do with Talgo. So all in all, from the perspective of testing Talgo’s claims, the trial was completed in 12 hours and 36 minutes. We used a diesel engine of the Indian Railways. For the trial on August 1, we had used an electric engine.” According to a Twitter post put out by Western Railway, Talgo took 12 hours 55 minutes.
Kumar told, “The maximum speed that we attained was 130 kmph“.

Now, for the August 9 trial, a maximum speed of 140 km/h will be tried, with the objective of taking 12 hours and 4 minutes. All eyes will however be on the August 12 run, which will be conducted at a maximum speed of 150 km/h.

Besides reducing travel time, Talgo’s lighter trains consume 30 per cent less energy which will help railways reduce their power bill.The Spanish train maker has offered to test run their lighter and faster trains free of cost.

TALGO (Tren Articulado Ligero Goicoechea Oriol, Goicoechea-Oriol light articulated train)

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 axle and 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 axles can change rail gauge – for instance at the 1,668 mm Iberian gauge/1,435 mm standard gauge at the Spanish-French border interchange.

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.
