Not that it is not interesting, but it doesn't feel very playable at all. Despite the fact that I love OpenTTD and like trains in general. By using real world information simple actions like buying track become extremely complex because in most developed nations tracks consist of many points and junctions. Even at the deepest zoom level, selecting the right piece of track is almost impossible.
Furiiku, sorry to hear that. You can also select a rail from the left menu if you have difficulties clicking it on the map. Once you start building a rail set, only available connections are filtered on the map so this should make selecting a proper rail easier as well.
After starting the game and choosing the difficulty level, I end up in the first level (I guess), but the controls don't respond at all. The game is unplayable.
The game was made to be hard, very hard... you can play on easy mode that removes collision with walls and increase a little your damage and the money dropped by monsters.
