At this point you usually have an extensive rail network, and the game doesn't provide good enough tools to make the process of replacing the old rails with monorails easy. At a certain year you can start building monorail. The AI is somewhat weak and compensates this by cheating a little (ie the AI doesn't have to pay for leveling land, since it's so bad at it that it would be ruined by the fees). There are also certain limits to the number of vehicles which may become irritating. The speed could be a problem on one of the slower 486:s, but that's not an issue anymore.
This is definitely one of the five games that I've enjoyed the most and spent the most time playing in my 17 years of computer gaming. Two-player mode is even more fun, but it's not always you have two computers and someone to play with. This, coupled with the fascination of watching all your little vehicles move around and checking the charts to find possible trouble-spots, makes for an enormous replay value. You always face new challenges whenever you start a new game. Perfect blend between realism and playability.
