So I've tried playing this game over and over again trying to get it right... it's kind of addicting that way! It's 3AM and I think I finally figured it out. I uninstalled the anti-traffic jam mod and the increased capacity mods, so it's basically all at default settings... the way we're meant to play it!
This is me August 1920 normal mode. 8 months into the game.

As you can see on the mini map my metro lines and bus lines already cover 50% of the city, and my income is at 12k.
Don't get me wrong, at first the game seemed pretty unbalanced (and probably is unbalanced lol), like for example:
When I first played this game, I don't know why I always start building my bus line infrastructure first, and play the rest of the game just trying to make money off it so I can build my metro line. well it doesn't work like that... why? because you'll clog your roads trying to keep up with demand and experience all sorts of problems.
So the key is to take as much loan as you can at first so you can build your metro line close to important spots of the city. then build bus lines around your metro line to increase your coverage area.
I think the game is pretty balanced once you know how to play.

Don't get me wrong, at first the game seemed pretty unbalanced (and probably is unbalanced lol), like for example:
- capacities are unbalanced
- too many people waiting in line
- vehicles getting stuck creating traffic jams
- ticket prices are unbalanced
- the budget is hard to balance
- overall the game is unabalanced!!!

- increase wages to happy face (green) to keep reputation up
- increase fares well beyond dark red to know your limits (balance with demand)
- lower fares when no one is using your system
- build metro lines as your backbone to important places, then build bus lines around it
