Computer and Video Games (CVG): "With its sheer complexity, vast, array of options, and immense scope for hours of play, Railroad Tycoon is one of those classiest simulations you're ever likely to see - a bit like SimCity with loads of extras thrown in."
PC Review Issue 7 (1992): "A completely unique game - and not just for trainspotters or overgrown kids either. Take control of a fledgling railway in the heyday of steam and use your best business acumen to take it across an entire continent - wiping out, or buying up, the opposition on the way. This forerunner of the superb strategy game Civilization is definitely not to be missed."
