The idea is to introduce the ability to set conditions before sending a train to a station. This will help optimize train routes and reduce the load on the railway network.
Here’s an example:
1. We have a depot station (A) where the train waits until the unloading station (C) is available.
2. Before that, the train needs to visit the resource collection station (B) to load cargo.
3. The route ends up looking like this: A → B → C.
Everything works fine if the train fully loads at station B and completely unloads at station C. But what if:
- At station C, only part of the resources is unloaded (e.g., 1000 units);
- And at station B, the train always loads to full capacity?
In this situation, the train might return to depot (A) with leftover cargo and then, on its next trip, visit station B again just to pick up the same 1000 units—even though it already has 9000 units on board. This is inefficient and unnecessarily loads the railway network.
The solution is to add a condition: before traveling to station B, the train should check if it already has at least 1000 units of the resource in its cars.
- If there are enough resources, the train skips station B and goes directly to station C.
- If not, it stops at station B, fully loads, and then continues to station C.
As a result, the route would look like this: A ? [B → C] | C.
This approach optimizes train routes, reduces the load on the railway network, and improves transportation efficiency.
If anything, I'm not an English speaker, so I used a translator.
And I also tried to figure out what it might look like in terms of visual
