Minimum transfers with night train not found

[t2gran]

Expected behavior

When searching from Fredrikstad to Trondheim with departure at 20:00, we expect to find the following itinerary:

• Train R20 20:44-21:51 from Fredrikstad to Oslo S and then the night train 21 22:45-06:28 from Oslo S to Trondheim.

Observed behavior

The only option found is R20 to Oslo S, then L14 to Lillestrøm and the the night train 21 to Trondheim. This journey have an extra transfer, so we would expect both results to be in he result set. The expected journey is not filtered away in the itinerary filter.

Some observations:

• The night train uses the old tracks from Oslo S to Lillestrøm allowing boarding the L14 after the 21 has left Oslo S and still catch the 21 at Lillestrøm - The schedule is: L14 23:04-23:14 and 21 22:50-23:20.
