The Vande Bharat Express was on its way from Varanasi to New Delhi in the northern Utta Pradesh when it ran into trouble.
India's NDTV reported that power went out in some coaches on the train, with a "foul smell and mild smoke" reported due to a "mechanical fault in the braking system" that caused the train to move at a sluggish speed.
There were no signs of damage on the front of the train, but it was stalled for about 2 hours before resuming its journey only to break down again, according to NDTV.
The train, which was carrying mostly railway officials and journalists, eventually made it to New Delhi where repairs are expected to be made.
The Indian-built Vande Bharat Express can reach a maximum speed of up to 110 miles per hour, Reuters reported.
The new train is expected to make its commercial debut on Sunday. The express train is expected to reduce the travel time between Delhi and Varanasi by six hours, according to the BBC.
