With much to think about, Tod went back to his home, which also served as the main control room of his new train service. The city''s population is mostly centered around the main core, and it gets less dense the further way from the core.
But, at-grade tracks (meaning surface level train tracks) are only possible in the outskirts of town, which is why the Tod had to pick carefully. The City''s quite dense, home to some 10m people, distributed over the 94 populated blocks, though there are small populations near the seaports.
Each block is equal to a 2.5km by 2.5km block, which gives the entire metro area a density of about 17,600 per square km. The demographics and density of this city lends itself to high-capacity public transport. In short, this was beginner-city.

But, high density areas cost more, because underground and elevated stations are only possible in these sectors. So, with Tod''s starting financial situation, it meant he could only do at-grade train services for now.

Tod went back to his spreadsheets, and crunched the numbers for the upgrades.

The results were clear. He would take the station retail outlets and station advertising rights immediately, since they paid for themselves so quickly. That meant he had to spend $200,000 x 3 stations, and $100,000 x 3 stations, for a total of $900,000
