Trains heading the same direction can cause deadlock at a junction.

[skybird-r]

Describe the Bug

Trains are deadlocked even though they are going in the same direction when chain mode signal is placed after a confluence point.
It appears to be occurring when a train attempts to enter a blocked section reserved for another train.

Reproduction Steps

1. Merge train tracks.
2. Place signals before and after the junction. Put later signal in chain mode.
3. Automated trains enter the confluence at approximately the same time.

Expected Result

No deadlock

Additional Context

Even though more signals or tracks are added, this structure will jam trains.

While this does seem like a bug, I think the signal setup is also playing a role here. Have you tried setting up signals leading into the junction into the chain mode?
