Pretty self explanatory request, spawning more rolling stock in yards would help make the railway feel busier, other than Tidmouth carriage sheds, a couple in Knapford and Vicarstown yard and Ffarquhar there doesn’t seem to be any rolling stock on the island Lines of trucks in the yards at Knapford harbour, Crosby, Henry’s Forest, or even the odd truck, van or milk tanker in the sidings at stations would make the world feel more alive
Some of those empty spots are likely saved for future rolling stock and services, like some log trucks for Henry's Forest and the Sawmill.
I might be oversimplifying here but it seems like it’d just be the case of replacing 1 line of code so instead of “spawn 4 troublesome trucks in siding 1” its “spawn 4 log trucks in siding 1” and that’d be easy to update when they release new content
