- Get as few train changes as possible. (Being a few minutes late is no issue if there are no connections to miss.)
- Any changes should be in big hubs. (You might be offered a route with a change in a smaller station, but if you miss the connection the next train might be hours off. If you change in a hub there will be many others.)
- Don't take the last connection of the day for the last leg of the journey, you might miss the connection and be stranded. Even worse if it's a small station (offices will be closed if there are even any there, there will be services like hotel and taxi somewhere but have fun finding them).
