When you want to travel from Station A to Station C, you would expect to buy a ticket going directly from A to C. However, you may find it a lot cheaper to buy a ticket from A to B, and then one from B to C. This means you could buy two independent tickets for the same journey, pay much less. The same applies to buying tickets more than two. What’s more, you may even find it much cheaper if you accept flexible journey. For example, buy two tickets from A to B and from B to C, with 10 minutes wait at Station B. These concept are what we called split tickets, and it helps passengers saving a lot money.
