I wanted to book a single 3AC ticket from VASCO to BHOPAL via 12779/Goa Express but it always showed PQWL for almost all dates in the month of February 2016. Due to some personal reason I wanted a confirmed ticket in this train at all costs, so I booked my 3AC Ticket from VASCO to NZM (Hazrat Nizamuddin railway station) and I got a confirmed berth in the train. Although I have booked my ticket from VSG to NZM, I will be travelling up to Bhopal only. I would like to know was this booking done right? Is this type of booking going to create a problem for me? I would like to know if this train switches/changes bogies at some station. Thanks in advance
