Hi My parents has counter railway tickets for this train in 2AC from ADI to BSB through Railway Pass on 21st Sep. But they want to board it from Mahesana (MSH) as they are currently staying in Mahesana with brother. Is this possible? We are afraid if TTE will give their tickets to someone else if they don't board from ADI or SBI. If in case answer is that boarding from MSH is not possible or on luck, can boarding of this counter ticket booked using Railway Pass, be changed to MSH?. Kindly help as its urgent!!
