There was a Railroad Tycoon 3, made mostly by the same team in the same office in Fenton. The changes to a more free-flowing tracks didn't necessarily make the game better, and were a headache for most of the production.

I was also told that there were attempts to make the economic simulation far more dynamic, simulating that the cargo could leave by other transport methods, as you'd find in a more serious economic simulation. That just made the game worse: The more efficient the market gets, the harder it is to find the profit, and the more likely that an old 'good' route suddenly stops making money, which is just annoying in a single player game.

It's a common problem with market-centric games: Good simulations make everything unfun, as most of the enjoyment comes from easily finding opportunities or getting away with misbehavior that would make real-life barons very difficult. This is IMO why you don't find many spiritual successors: Most steps forward would be steps back when it comes to making the game fun. So you'll find games focusing just on the tracks, but as puzzles (like the Train Valley Series). Optimizing routes trading items (spaceways), or outright market manipulation (Offworld Trading Company). Doing it all at once basically demands copying the game with newer graphics.
