En Route map doesn't show journeys from/to FF

[jeyemwey]

Describe the bug
The en route map sometimes doesn't show journeys from/to Frankfurt(Main) Hbf and/or they're longer than 1h. I don't know why, and I don't know how, but that seems to be the only connection between all journeys that are hidden.

To Reproduce
Steps to reproduce the behavior:

1. Check into any train from/to ds100:FF.
2. Open the "en route" page.

Expected behavior
The polyline is displayed

Screenshots

Desktop (please complete the following information):

• OS: Windows 10
• Browser Firefox
• Version 73

Additional context
The issue sometimes happens on other journeys, too - so I guess it's another flaw.
