Protesters squatted over rail tracks, stopping the Delhi-bound Amritsar-New Delhi Shan-e-Punjab and Amritsar-bound Saharsa-Amritsar (Jan Seva) Express, railway sources said.
Protesters also raised slogans against Congress-led UPA government, especially against Sajjan Kumar and Jagdish Tytler, "discriminatory justice system" and government's move to hang Devinderpal Singh Bhullar.
Both trains were allowed to leave the station, a little after 6 pm.
Protesters, who earlier assembled in Prem Nagar Gurdwara on Khera Road and then marched towards the railway station, also burnt effigies of Sajjan Kumar and Jagdish Tytler.
