The new environments came with different industries and challenges. The deluxe version also expanded the game to provide tropical, Arctic, and toy-town environments, as well as the classic temperate environment.

This is a highly used strategy because it allows for intercontinental transport of goods which results in high return rates for the user. It also unlocked the ability to build continental-length railroad systems by incorporating one-way rails in both directions and the ability to merge other rails with the main one. By incorporating both uni-directional and bi-directional signals, effective switching yards, junctions, and other useful designs could be built. This allowed for efficient routes to be built, and prevented trains from trying to travel the "wrong way" down a section of track. The new uni-directional signals allowed one-way tracks to be built, which gives the player much greater control over how the railway network could be run. While this would not result in crashes on a properly signaled route, it required either the building of extra track to allow the trains to pass each other, or the building of a great many tracks in parallel to avoid the problem in the first place. Unsurprisingly, it was possible for two trains to try to travel in opposing directions towards each other on the same run of track. This is similar in concept to having a single lane street that would allow traffic from either end. The change in gameplay from this relatively minor alteration to signals is significant, as the old bi-directional signals would allow a train to travel in both directions. The deluxe version introduced uni-directional signals, that only allow a train to pass in a single direction. The original Transport Tycoon allows only bi-directional signals, which allow trains to pass in either direction. The primary difference between the games is how signals operate. (A "World Editor" expansion pack was also released for the original Transport Tycoon, but was overshadowed by the Deluxe version released shortly afterward interestingly, it featured an alternate, Martian set of graphics, which did not appear in TTD). The deluxe version, as its name implies, is an expanded and improved version of the original game. Two Transport Tycoon games were released, dubbed Transport Tycoon and Transport Tycoon Deluxe. Please see the VGG entry for the original Transport Tycoon for more details.
