A-Train HX

To win every map I builded a lot of convenience shops. To do this I used some basics from borandi's guide:

Go to the edge of the map and search an area without water and mountains. It has to be a large, plain area.
Near the edge of the map (7 squares away), build a Marshalling Yard with five platforms (It has to be a long one, no short) (press to change the number of platforms and length of platform), with the barriers of the station facing into the main map. Now fill up the empty space between the yard and the edge with rails. Next build large Material Yards around the station. I used two rows of large material yards right under the station and one next to each side of the station.

You're going to need 5 Model EC6 HS Goods Trains on the rails with each 7 carts. Also make sure all trains are set on UNLOAD only.

Now let your trains do the job and get some materials.

If you only have a small amount of money you can lend some from the bank (as much as possible).

Now start building convenience stores (under construction mode - shops) Build them around the station as much as possible. After a while these stores will give you a lot of profit. Just make money and build new stores. When you have a lot of properties and around 6 billion on your account, you can either go to market and sell your properties or you can lend some more at the bank untill you reach 10 billion.

Once you reach 10 billion you will get a notification to enter the leaderboards. Just accept, this means you finished the map.

Also be sure to keep an empty save slot for each single map. As soon as you finish the map, save it and keep all your saves (don't overwrite them). In the load game screen all finished maps (slots) have a yellow background. Maps you didn't finish yet are white.

I found this method rather easier and much faster then playing the stock market which is actually based on luck and pretty boring to watch.

There is one map though where you have to play the stock market because there is no suitable area to build on the edge: name of the map: A Beautiful Archipelago.

This is a buggy achievement. Once I finished playing all 8, this didn't pop. I had to go back and delete all of my save data and games and do this again. By then, I had the routine down pat, but it was extra time that I shouldn't have had to spend.

Just a heads up.
