Based on the provided text, what was the initial reaction of Madhavrao and Dixit when they saw the crowded train, and what was the ultimate resolution?

Upon reaching the station at ten o'clock, Madhavrao and Dixit saw that the second-class carriage was 'packed to capacity.' Their initial reaction, as detailed in Chapter 51, was one of 'deep worry.' The situation seemed hopeless, and with very little time remaining before the train's departure, they both decided that their only option was to abandon the journey for that night, return to where they came from, and try again the next day. However, their problem was resolved just as suddenly when the train guard appeared. He recognized Dixit, and without any worry, he arranged for both of them to sit in the first-class carriage, turning their despair into a happy and comfortable journey.
