Simple Train Journeys

Age 5 to 11 Challenge Level:
How will you record the different journeys?
Have you got a way of making sure you have got them all?
Perhaps there is a way you could use the three-station journeys to help you find all the four-station journeys?
When you're looking for a pattern in the numbers, it might help to go even simpler as well - how many journeys would there be for just two stations?
Can you see any way that the numbers of different journeys are connected to each other? It might help to write them in a list or table.
