Good news, the game is AWFULLY unbalenced right now with the USA DLC. I was playing nicely through the 30’s, having made 100m in the bank and was enjoying my ’empire’, then suddenly, almost ALL the lines started loosing money and I didn’t recover until 1950. This was due to a HUGE running costs of the later rolling stock and the fact their costs seem to double as they get older later in the game, not, as my girlfriend asked, anything to do with WW2 breaking out!
