Passenger stations should be placed first near residential areas and then near any possible destinations like the places of work or commercial centers. I learned all of the following through observations and much Trial/Errors. This guide is meant to help solve these problems.
Eventually the entire rail system would come to a grinding halt, as a myriad of cargo and passenger trains would block each other’s path. All they seemed to do is cause traffic jams on my streets, fail to deliver enough of the citizenry and cargo to the various destinations, and general provide a giant pit to throw money into and burn. I struggled at first with making my trains operate in an optimal manner.
