I strongly believe 1 of Delhi bound train from East will be extended till BTI or SGNR as soon as election is over in Punjab. It may not be daily but will be 3-4 days a week. Most likely it will be a HWH bound train only to compensate 3007.
शरबत एक्सप्रेस which is this?
Delhi to Lohia khas/Moga via Ludhiana
