Sachkhand took Chandigarh route only for a brief period of 3-4 months.
It used to catch up with Paschim from Ambala Cantt onwards and then followed it till Amritsar via Chandigarh.
For that brief period its Amritsar Arrival time even after taking a longer route of Chandigarh used to be 20.15 PM.
When...
more... it got re routed back via Sirhind-Rajpura, it was given a different slot between Manmad and New Delhi resulting in slow down of 75 minutes in that section, since then it has further slowed down by 30 minutes in Ludhiana-Amritsar section in last 12 months, pushing the ASR arrival time to almost 22.00 PM.
