I had a city with 25000 citizens, but it started to decline. As you can see on the screenshot there're a lot of empty spaces. There used to be building along those roads.

To prevent the decline I added bus routes within the city. According to the OpenTTD wiki that's a way to increase town sizes:

A bus with one passenger from the other side of town would have the same effect on growth as a large train full of passengers from the other end of the map. source: wiki.openttd.org

But the city still shrinks. Those somebody now how to prevent this?
