A good start anyway, Otviss.

I think, that building railways is quite expensive in any time, so it´s logical to lower the costs by shrinking the lenght of your railway system. I think half the lines would do good for your country, because many routes could be optimized and some lines could be put together. What about some major lines from city to city, catching as much of them as possible. Then there would be enough space (and money) to connect major cities to its neighbor-cities. So when you have to travel from your south east to the southern middle, at the moment you have the choice between three different lines which are lying quite closely together..
