Trains can stack to an unlimited quantity if you place a looping.

Rail loops break the space path update order calculation in some cases
To Do • Priority: Low • Fix: None

Rail Loops break the space path update order calculation in some cases. The issue occurs when Rail Loops are present in the rail network, causing the game's pathfinding system to incorrectly calculate the order in which Space Platforms should be updated. This affects train routing and can lead to unexpected behavior in rail systems that include loops. The specific trigger conditions are not fully detailed, but the problem is known and tracked for future resolution.

Train loops on small rail piece
Done • Priority: Medium • Fix: Future • Resolution: Cannot Reproduce

A Train / Rail vehicle is looping on a small Rail / Train track / Railway piece in an unexpected way. The user observed this behavior but does not know how they triggered it and cannot replicate the issue. The loop appears to be an illegal or unintended state, as referenced by the Discord title mentioning an illegal Train loop / Rail Loop. This suggests the Train / Rail vehicle is stuck in a looping motion on track geometry that should not normally support such behavior.

Train won't leave wagon transfer station when delivering more packages than the station can have
Done • Priority: Highest • Fix: Dimension Update [0.1.0] • Resolution: Done

When a Train delivers more Shape Packages to a Wagon Transfer station than it can hold (exceeding the maximum of 7), the station accepts up to 9 packages but the Train becomes stuck and won't leave the station. This occurs specifically when the delivery would cause the station to exceed its normal capacity, such as delivering 3 packages when 6 are already present. The Train remains stuck until another Train removes packages from the other side, reducing the count to 6 or below. Normal behavio...

Trains can spin on Train Deposit
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

Trains can get stuck spinning on the Locomotive Depot when rails are cut and reconnected. The issue occurs when a player places a Locomotive Depot with rails, cuts the rail in front of it causing the train to loop on the depot, then reconnects the rail. After reconnection, the train continues looping on the depot instead of proceeding onto the rail as expected. This prevents normal train movement and routing.

Trains can glitch into each other
Done • Priority: Medium • Fix: 4 - Early Access • Resolution: Done

Trains can phase through or overlap with other trains on the same rail track. This collision glitching should not be occurring due to the implemented train collision avoidance system. The expected behavior is that trains should properly detect and stop before colliding with other trains ahead of them on the track. This bug undermines the train routing and safety mechanics that are supposed to prevent rail vehicle conflicts.

Trains spinning when returning to base
Done • Priority: High • Fix: Dimension Update Patch 1 [0.1.1] • Resolution: Done

Trains keep spinning when returning to the Locomotive Depot after cutting a Train Launcher and rebuilding it over level 2. The issue occurs when creating a train with 3 wagons on level 1, raising a 3-tile rail section to level 2, attaching a ramp for minimal jump height, then cutting from the elevated rail to the ramp end, leaving two spaces, and filling those spaces with rails. The expected behavior is that trains should return normally to the depot without spinning continuously.

[SPZ2-5801] [0.1.1] Loops allow for unlimited train storage

old moat
#

can confirm this bug still persists in 1.0.0-A3-RC1

#

something of note, the trains cannot have more than 3 wagons

#

this same behaviour also happens for train launchers as well

#

this only works if the gap between the launchers is less than or equal to the number of wagons the train has

#

this effectively limits the train size this works for to 4. anything larger and you can't infinitely stack them.

Interesting. That isn't related to the train loop though. Is there an existing bug report on discord talking about it happening for rail launchers/catchers?

old moat
#

no, i was going to make one but found this. i'll make one for launchers too

Nothing found using a search though.

#

yeah i just made one, the closest one the bot found was this post

#

they may be related, but who knows what goes on behind the scenes
