The LNER service between London King’s Cross and Edinburgh stopped at Newark, Nottinghamshire, because of damage to overhead electrical wires.
A journalist, Laura Foster, who was on board, said some passengers fainted when the lack of power cut off the air-conditioning.
LNER and Network Rail have apologised for the problem.
The issue has been hampering services between Doncaster and Grantham on the East Coast Main Line since about 15:00 BST, with a number of cancellations.
Ms Foster said: “We were all absolutely sweltering in the heat before staff managed to open a few carriage doors.
“When people started fainting, their fellow passengers rallied round to share water and make sure they were OK.”
A LNER spokesman said: “We apologise to customers for disruption to their journeys today. This is due to damage to the overhead power lines in the Grantham area.
“We are working with Network Rail to get trains moving through the area and wherever possible are diverting services until engineers are able to fix the problem.”
He further added that two trains were stopped and both were now at Newark North Gate station.
