There will be two more trials on the Delhi-Mumbai section.
Spanish-made Talgo train today completed its Mumbai journey 17 minutes behind schedule due to a technical glitch.
The Talgo train with nine coaches had started at 2.47 pm from New Delhi station on Friday and it reached Mumbai Central at 3.40 am on Saturday running at a speed of 130 kmph.
It took about 12 hours 53 minutes to reach the destination against the target of 12 hour 36 minutes, said a senior Railway Ministry official.
Besides heavy rains, there were some signal problems during the Mumbai trial run which caused the 17 minutes delay, he said.
There will be two more trials on the Delhi-Mumbai section.
Talgo is expected to run at a speed of 140 kmph on August 9 and at a speed of 140 kmph on August 14, he added.
Talgo aims to reduce travel time between Delhi and Mumbai by four hours. Currently, the super-fast Rajdhani Express train takes around 16 hours to complete the 1,384 km stretch between New Delhi and Mumbai.
Railways had conducted the first trial run of Talgo trains on the Bareilly-Moradabad stretch in Uttar Pradesh in May. The second trial run was conducted on the Palwal-Mathura section of the North-Central Railway.
The nine-coach Talgo train consists of two executive class cars, four chair cars, a cafeteria, a power car and a tail-end coach for staff and equipment.
