Before you go aiming for the achievements, you first should follow the tutorial what will start at your first game. This will explain you everything you need to know about the game. If you don't follow it you might can get confused how everything works.
Also I would advice you first to play the game through campaign or with your friends in co-op. On this way you will already obtain some achievements and enjoy this great game much more.

Also important to know is that the achievements can have a delay before receiving them. So even if you done the requirements for a achievement it can take to maximum 30 seconds (mostly it will be faster) to obtain your achievement.
Either you can't see the progress how far you are away from a achievement.

To make the achievements even easier to obtain, you can make a sandbox game with unlimited money.

All these above are easy obtained by making running lines. Each lines has to have atleast 2 stops. But these lines doesn't have to be unique, so you can make 25 lines on 2 stops. Just be sure you do all these achievements in one game and not spread over different save games.

We Can Build It!

Money, Money, Money - 2
Have 300,000 money


Money, Money, Money - 3
Have 1,000,000 money

To get the first two done real quickly, you start a new game. Take a loan of 200,000 money. This with your starting money of 100,000 will make a total of 300,000 what will give you, your first 2 achievements.

For the last one of 1,000,000 money, its easiest to use the map and ruleset below (same one for Like Sardines). Then build two lines (both directions) and build enough busses. When you got around 150,000 money you can take a lone of 850,000. This will come on a total of 1,000,000 money.

This is your overal time you played this game in real hours (so no game hours). Get to 60 hours and you will get the last achievement. Although the time doesn't counts if your AFK (Away From Keyboard) in the main menu. So you need to be inside a game. Pauzing the game might will stop the counter too.

Top Dog
Have 100% reputation

A few things that will help you get to 100%:

• Have all ticket prices to 0.00
  
• Make all workers 100% happy
  
• Use a small map (less people = less worries)
  
• Cover the whole map (make every building green, not yellow)
  
• Take your time to let the reputation grow to 100%
  
• I used Tutorial City for this, although I removed the house on the total right of the map

Got more information? Post it below.

No Friend Of Mine
Have 0% reputation

For this achievement you need to set ticket pricesses to the maximum (so not only to red, but really to the maximum). At the employees you set the wages to 0. The allow overcrowding to 100%. Now you need to wait maybe around a hour or so to let the population drop down to 0% (this can be done AFK).

''I got this in just a few minutes by creating a very small map using the map editor. Build 1 building and surround it with an encircling road.

Load up the map in a sandbox game and disable city growth. The achievement should pop up eventually. It will help if you don't have any lines set up.''

Modern Days
Complete the campaign Modern Days

Simply complete the campaign Modern Days.

Opprinnelig skrevet av b88: Not the Mama:

For the campaign, I would just build a metro line running through the major areas of the map, taking out loans of 200K at the start. With enough money leftover, another metro line running bisecting it and those 2 lines should give you enough money to do whatever else you need.
Keep an eye on what the objectives are. For city/population growth, build roads with sidewalks in undeveloped areas. For coverage, tons of bus routes.

Green City
Have no private motoring in the city for 48 game hours

For this achievement I would advice you to use the map "Tutorial City". All you have to do is remove all the roads and speed up the game. While waiting all buildings will dissapear what will be no problem. Wait of 48 game hours (not real hours).

The Cover-Up
Have 100% coverage

For this achievement I would advice you to use the map "Tutorial City". For this achievement you not only need to get every building green (2 lines at every building) but you also need to use every piece of road. The screenshot below will shows how I did it.

Opprinnelig skrevet av Der_Adler:

Found an easier way to get "The Cover-Up". You can simply destroy great part of the Tutorial City, just leave a couple of areas. So you can get 100% coverage just with 1-2 bus lines.
