3D Ultra Lionel Traintown is a simulator that provides access to the construction of any railway. To do this, the hero will receive all the necessary resources that need to be distributed to specific tasks. Construction takes place in stages, first you need to build the road itself, lay rails and sleepers, set up logistics and put the environment in order, ensuring safety for the trains.

In 3D Ultra Lionel Traintown you need to install stations where trains will arrive. There is also the possibility of maintaining broken cars. For this purpose, a workshop is being built into which trains requiring repairs and inspection will call. In addition, there are mechanics for controlling steam locomotives. In order for them to last longer, you need to cool them with water in time. This way they will be protected from overheating. Also, the hero will refuel them along the way.

Besides construction, the main goal of the game is to transport goods. Transportation and loading of wagons is done manually. For this purpose, special mini-games have been developed where you need to fold items correctly, and so that nothing happens to them during transportation. Also, during the route, random events may occur that will affect the delivery time. The hero needs to quickly solve the problem that arises in front of him. For example, a lot of sheep will run out on the road or even aliens will fly in and try to break the road.
