Describe the bug

Train "S 8 (16625)" Dresden Hbf -> Kamenz(Sachs), on 2024-12-17 (and other dates), 16:35, misses realtime data and shows as "S 0" and as "unbekannter Zug" when clicking backwards and forwards one day.

To Reproduce:

1. Search for a train connection from "Dresden Hbf" to "Dresden-Klotzsche" for e.g. 2024-12-17, 16:35 (issue also appears on other dates, future or past).

2. Open the connection 16:35-16:50 with train "S 8":

3. Klick on the train "S 8"

4. Observe that the URL actually calls it "S 0"

5. Observe that no real time data and no forecast data is shown:

6. Click back one day

7. Click forward one day -- should now display the same train again

8. But observe that it just shows an error "Unekannter Zug", and calls it "S 0" (actually, does it already after going back one day):

Expected behaviour:

• See real time data
• Have the train called "S 8"
• Arrive back at the same train when clicking back and forward one day
