I live in the greater LA area so I often use Google Maps to scope out urban and industrial areas to gain ideas about what to create my city around. Only recently did I see this on GMaps, https://maps.google.com/?ll=33.882432,-118.216377&spn=0.007936,0.013937&t=h&z=17 , its a freight railway that provides direct access from Long Beach port and helps connect it to the port of LA and then to the interior of the state and so on. Its a sub surface rail the goes through the middle of two streets. Its known as the Alameda Corridor and stretches about 20 miles, allowing an unobstructed traffic flow for cars and what not.
Ive tried just using hold digger lots and bridges but it seems kinda, 'half baked'. I do use mods(NAM, etc), so that isnt a problem, I just want to know if anyone can point out some specific ones or other ways to give this a more legitimate look. I want to place this in my current city of about 300,000 people directly through my industrial quarter that leads from my ports to some railyards I have set up in the inland.
Thanks for any tips!
