What is meant by Day 2 / Day 3 etc. along with time under the Arrive column?
Some long distance trains may arrive at their destinations on the next day or the day after. This is indicated along with the arrival time. For example, a train departing from station A on 1-May at 17:00 may arrive at its destination, station B on 2-May at 10:00. Hence we would mention the arrival time as 10:00 Day 2 to indicate that it arrives at 10:00 the next day.
