OMMCOM Exclusive: Hear Odia Technocrat Debi Prasad Dash, A Key Man Behind ‘Train 18’
Bhubaneswar: India has high-speed trains like Gatimaan, Shatabdi and Rajdhani which are capable of running at 140-160 kmph. These are 'loco-haul' trains that have an acceleration capacity of 0.3 metre/second-square, whereas the Train 18 has an acceleration of 0.7 m/s-square.
Therefore Train 18 gains speed faster and reduces the travel time between stations, than loco-haul trains, Debi Prasad Dash, Chief Design Engineer (Electrical) of Train 18 said.
In an exclusive interview to OMMCOM NEWS, Dash who hails from Odisha's Jajpur district said that building Train 18 – ‘Semi-high speed world class train’, was a big challenge, and the entire team lived up to the challenge with competency and perfection.
“When you do something for the first time, there are no references available. Therefore it was a big challenge for the entire team to start from the scratch,” he said.
Acceleration and de-acceleration are two defining factors of Train 18. With a faster acceleration Train 18 reaches 100 kmph in 150 seconds and 160 kmph in 182 seconds.
A similar principle applies to the application of brakes. Train 18 can de-accelerate at 0.8 m/second square. That means it can arrive close to a station at a high speed and brake instantly to come to a halt. It reduces the time for braking, Dash added.
Out of the 16 coaches in this train, eight coaches are fitted with traction motors, fixed on the wheels. All the instruments are not limited to the locomotive, but distributed over eight coaches. This is a big difference between other high-speed trains and Train 18.
