Your train ticket is valid on the day of travel and remains valid until 04.00 in the morning the following day. In other words, if you plan to catch a train at 21.00 in the evening, you can continue to use your ticket until 04.00 the following morning. If you plan to catch a train at 10.00 in the morning, you can still continue to use your ticket until 04.00 the following morning. So if your plans change during the day, no worries! This gives you stress-free flexibility to plan your day the way you want.
