Hey FruitBerry!
That's a nice idea you got there but it have to wait. We are close to the next update and need to focus on it. I do like to create such a train, because it should be simple and easy. But at the moment I have no time to work on it.

This guide below describes how to use the SW Mini Trains.

---

The first thing you need is a layout. Build your own railway or use one of the two maps. Spawn your buildings to create delivery routes. (On the picture below)

You can see the necessary wagons on the building signs. (Right side on picture below) Each sign shows what is produced and consumed. Consumed loads are processed into products over time. After that you can transport the new products with the correct wagon to the next building.

Delivering wagons from building to building will generate experience. Each building will gain experience if you deliver or pick up waggon loads. Be sure driving slow over the metallic round plate in front of the building. That's the wagon sensor. (Left side on the picture below). Drive fast to skip the load or unload process.

The max level a building can reach is level 6. Except cities. (Further infos below) The production time is 10 seconds and will be divided by the building level.
Example: The building is level 4 so the production time is 2.5 seconds.
The storage of each building is also adjusted with each level.

Cities are the end consumer of all product chains. All cities can reach level 11. The production time for cities is 20 seconds. They work with the same principle as the other buildings in relation to produce time and storage.

If the building storage is full, it will no longer accept wagons loads. If products are not shipped away, the resource storage will also start to filling to the max. (On the picture below)

So be sure the product get consumed! Otherwise you stay on a your filled wagons loads.

All buildings and wagon loads can be saved via GMod savegame or duplicator.
Also supported are ADV1 Duplicator and ADV2 Duplicator. So all your progress will not be lost after you close the game or if you want to take a break.

If a building reaching the max level, feel free to push the experience bar to the limit! Just for fun!

Closed as solved.

Closed because no further details were given.
The error was not able to reproduce on developer side unfortunately.
