The train, which left Amritsar station early Friday, was stranded at the Ludhiana station with over 600 Delhi-bound passengers, police officials said.
Police and railway officials were trying to persuade the protesters to lift the blockade and allow the train to proceed.
Over 3,000 Sikhs were killed in Delhi and other places across India in anti-Sikh riots that broke out following the assassination of then prime minister Indira Gandhi by her two Sikh bodyguards on Oct 31, 1984.
Sikh organisations have lamented that even 25 years after the carnage, the guilty have not been punished.
