It is the best train to travel from Amritsar / Jalandhar to Delhi in the night. One Tip though if you try to book Tatkal ticket from Jalandhar it will show N/A in Sleeper so Book Uptill Mathura and you will easily get the Ticket and Sleeper Coaches are clean uptill Nizamudin , I have travelled a lot of times from Jalandhar to Nizamudin By Booking in the same manner. Maintains time most of the time uptill Nizamuddin.
