What happened to the Noolkar and Dixit families when they tried to leave Shirdi, according to the events described in Chapter 9?

A note within Chapter 9 details an experience of the Noolkar and Dixit families. Sai Baba had instructed them, "Go tomorrow morning and eat at Kopargaon before leaving!" They prepared accordingly and even arranged for a meal to be ready at an eatery in Kopargaon. However, upon reaching the town, they found the meal was not ready. Since the train's departure time was near, they proceeded to the station without eating. There, they discovered that the train was delayed by an hour and a half, a turn of events that validated Baba's mysterious timing and instructions.
