Maybe some kind of protest on Amritsar - Beas section.
Some trains were diverted via Amritsar - Tarn Taran - Beas section.
3 trains - 18310, 15934 and 18238 were diverted via Pathankot Cantt - Jalandhar Cantt.
Rest all trains after Chattisgarh Express departed late from amritsar on their original route that means protest was lifted later in the evening.
