even the pinned post isn't solving

Make sure:
• You got a track builder from the disassembled category.
• You have a large enough truck to carry the track builder.
• The line isn't set to "wait until loaded" at the customs.
• There is a path between customs and the RCO.

If that doesn't solve it, then please post some screenshots or a link to download your save.

I'll see if I can post the link, all of the above four items were done. The only thing that I think it could be is that I might have unlocked all research on this play through.

There was a bug that made them not loadable when purchased before RCO was built... it was fixed but maybe a resurgence? (shoot in the dark)

I built my RCO first, the only thing I can think of is the research unlock

I'm going to start a new game that is purely realistic mode to see if I can isolate that as the problem

hmm lets see, the vehicle wont pick it up if there is no RCO on the list of stops. Maybe you are trying to move the builder to a road depo first? It has to be delivered direclty to RCO.

ps: no need to do it in realistic, the mechanic exists in normal mode as well (might be easier to set up a test)

Nope I have it going directly to the RCO

i think a lot of people play or at least tried realistic, so we'd pick up a bug by now. It has to be something stupid or possibly mod related. No research should be needed.

Only other thing that comes to mind is you managed to luck into used track builder (two buttons are close) and it has some kind of a rare issue.

The open hull is being sent from a road depot to the customs house to the rco. It's an RTTN, to pick up a disassembled track builder that the truck is capable of carrying.

yup all checks out, make sure the load order has vehicles selected, and wait till full is disabled.

Make sure you do not specify a certain type of vehicle, as that can cause it to not pick up the track builder.

That's a tricky one.
You have purchased the track layer?
So you can see it in the list down there when click at the custom house?
The truck is heading out to the customs?
It just failes to load the track layer?

I'm highly interested in screen shots and/or your save.

Is there any research that even has an influence on rail or rail building? Unless you built a rail distribution office instead of construction office...
