New Delhi: The speed of trains connecting major metro cities would be increased up to 200 kilometres per hour (kmph) on nine select railway corridors in a bid to reduce travel time, Railway Minister Suresh Prabhu announced today.

"The speed of nine railway corridors will be increased from the existing 110 and 130 km per hour to 160 and 200 kmph respectively so that inter-metro journeys like Delhi-Kolkata and Delhi-Mumbai can be completed overnight," Prabhu announced while presenting his maiden Railway Budget in Lok Sabha.
