Raised my salary again.
What to do with all those cash? Let's invest in business. Bought the Meat Packing Plants and the cattle yards. They will replenish the money spent on them in about a decade or so (the profitability changes, at the latest save the Meat Packing Plant produces $57K yearly). After that it's all profit, no maintenance n shit.
It was time to develop Huinan's station: restaurant, saloon, hotel - to increase passenger revenue -, and telegraph poles to cut down turnaround (I think this influences how much time is spent at the station by the trains, but not sure.)
