Th trials of the bullet train will be conducted at a speed of 350 kilometers per hour, comparable to the take-off speed of airplanes, officials. The first such trial will be held between Bilimora and Surat in Gujarat in 2026, followed by other sections, they said. The operational speed of the trains will be 320 kmph.
