When I destroy a span of railway and reconnect it, trains won't go through that span of railway anymore, they turn back or turn to another side instead. Can somebody tell me what kind of bug i'm facing an how to fix it ?

I wonder what is a realistic city size? I want to make massive ones but i get bored i run out of buildings and ideas after awhile can anyone help? A realistic scale of a city? Depend? Some cities in the world are very small, and some are very large. But I think Colossal size is the best for cities ...
