At Mari's suggestion, im making a separate thread, sorry if it turns out to be a duplicate.

If you place a Shape Unloading Station in the MIDDLE of a set of track, and place Shape Loading Stations toward the END of the same set of track, the Preview will only account for the Loading Stations set up BEFORE the unloading Stations

1. [SPZ2-5304] — 👀 72% similar

Train predictions are accounting for all loaders when the shapes will never get to the unloader they are indicated on
Done • Priority: High • Fix: None • Resolution: Missing Feature

Train Shape Previews show all loaded Shapes on every unloader even when those Shapes will never reach certain unloaders due to earlier drop-offs. This occurs when a Train picks up Shapes, drops them off, picks up different Shapes, and drops those off - all unloaders display predictions for all loaded Shapes regardless of the actual route. The user expected predictions to accurately reflect which Shapes would reach which unloaders, but this was closed as working as intended since precise predi...

2. [SPZ2-5783] — 👀 65% similar

Train transfer stations are blocking predictions
To Do • Priority: High • Fix: 1.0 Release [1.0.0]

Wagon Transfer stations block shape previews from propagating further along the train network. To reproduce, start a new Classic Mode savegame in the Regular scenario, enable cheats, place Wagon Transfer stations in a train setup, and use F9 to speed up shape delivery. Shape previews are missing after the Wagon Transfer stations. The expected behavior is that shape previews should continue from the Train Launcher all the way to their destination.

#

3. [SPZ2-5303] — 👀 60% similar

Prediction for trains that have more wagons than the amount of loaders will be showing for the wrong unloader
Done • Priority: Highest • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Done

When a Train has more Wagons than Shape Wagon Loaders at a Train Station, the Shape Previews display on the wrong Shape Wagon Unloader. The previews appear on the first unloader instead of the last one that will actually receive the shapes. This occurs in Classic Mode when setting up a station where the number of wagons exceeds the number of loaders. The previews should indicate which unloader will receive shapes based on the train configuration and loading pattern.

#

4. [SPZ2-5308] — 👀 55% similar

Unloader without a train stop does not forward predictions
Done • Priority: High • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Done

Shape Wagon Unloader does not forward Shape Previews when placed without a Train Stop. When a Train Stop is present, the previews work correctly, but omitting it causes the prediction forwarding to fail. This affects the ability to see what shapes will be output from the unloader in advance. The issue has been fixed as of December 9, 2025 in build [token redacted].

#

5. [SPZ2-5299] — 👀 52% similar

Predictions don't show if a train has less wagons than the amount of unloaders
Done • Priority: High • Fix: 1.0 Bugfixes before Feature Freeze • Resolution: Done

When a train has fewer wagons than the number of shape wagon unloaders at a station, shape previews stop displaying on the unloaders. This occurs when rail tracks are modified to add extra unloaders beyond the train's wagon count. The expected behavior is that previews should still show for unloaders that can actually receive shapes from the available wagons. The issue was reproduced in Classic Mode by placing a train station, then replacing a rail segment with an additional unloader. This pr...

Filler wagons block train predictions from shape/liquid wagons attached afterwards
To Do • Priority: High • Fix: 1.0 Release [1.0.0]

Spacer Wagons block Train Shape Previews from Shape Wagons and Fluid Wagons that are attached after them in the train composition. When a train has a Spacer Wagon followed by Shape Wagons or Fluid Wagons, the Shape Previews do not display correctly for the Shape Wagon Unloaders and Fluid Wagon Unloaders connected to those wagons. This issue can be reproduced in Classic Mode on Regular scenario by placing a train with this wagon configuration. The expected behavior is that Shape Previews shoul...

@supple dagger Thank you for your report! Do you happen to have a train transfer station as part of that train track?

supple dagger Mar 16, 2026, 8:06 PM

#

No

Just loaders and unloaders

zinc dragon Mar 16, 2026, 8:37 PM

#

Then this might be a new issue. Would you be willing to share the savegame or the BP occurring?

supple dagger Mar 16, 2026, 8:37 PM

#

when I check something in a minute yeah

#

Sakra I thought this would happen. While the issue appeared to fix itself on reload, I removed and replaced the stations resulting in in the previews working again.

Doesnt change what I saw happen, and (since we are here) Im gonna see what happens if I do that to ALL stations on the line

#

Nope

#

but I know what I saw, and I sent in a screenshot to prove it at the time

zinc dragon Mar 16, 2026, 8:58 PM

#

Previews will sometimes not appear on the unloaders if the loaders do not have the stop placed, is it posible that they might have been added after the picture was taken?

supple dagger Mar 17, 2026, 2:47 PM

#

Nope. I always place stops while building the stations - otherwise whats the point.

My money's on this being a subtler issue, maybe you can build a track with an unloading station in the middle, then see if previews are firing on your end? Specifically I build the unloading station LAST

I have a suspicion. Can you replace all the wait stops with immediate stops and see if the problem persists?

#

All the wait stops connected to that rail system I mean. You don't need to do it everywhere.

#

it does look like it fixes it at first glance - but undoing the changes also showed the previews still working. That, and since this was posted there was an update to the beta which had me choose a graphics setting. So Ive got no real clue if there was a change chucked in during the update
