My main industrial strategy was to build my own upgraded Textile and Lumber Mills next to those that I had already connected. This meant that those places were really pumping out cargo (for example, 32 Textiles per year) which kept the price there low and my trains made a good profit hauling cargo away. In fact I had to expand to new places as even prices in the cities were stagnant and had a big shipment of 20 trains mainly full of 40k plus Textiles and Lumber in year 9 that boosted profits to 7.1M that year. I believe that playing this to the potential of the resources on the map with this high output resources (3x normal output) is going to overwhelm all demands on the map pretty quickly. On the industry front I managed to build a Tool and Die, then a Distillery, followed by two more Tool and Dies, but that was the end of the game. I never even thought about taking a book value hit from buying access to any cities. That would be a serious setback. There is mention of the express cargo paying well. Sure, but you need at least 3 cities and preferably 5 connected and then wait a year or two for passengers to "discover" the route is active.
What can I say, good concept. Fun to play with high output industries and farms/mines, but not a challenge as far as the economy.
But that is a good reason I couldn't find in the Archives as OLs or NA scenarios.
