Well, I start off good, I have good mayor rating, everyone has jobs, no problems whatsoever. Then I expand a little bit, and everything slowly goes downhill. Soon, residents will have no jobs. Their commutes will be long. Some houses will even be abandoned due to long commute. Sometimes commercial zones go abandoned due to low desirability. I build highways and avenues, but I think the problem stems from not having a good rail or subway system built. I usually stray away from those since I cannot create a successful transit system. Do you guys have any good tips on how to create a successful rail/subway system, and any tips I can use for keeping my city running smoothly? All help is greatly appreciated. Thanks!
