Smr Simple!

Hi everyone, I´m new, and I need help...
I want to create a map with all the industries, but I can only put a few of 20...
If you can help me, I would be very thankful
Have a nice day

Suggest, you read the Wiki. There is a link at the top of the page header.
Just to caution you. There are certain limitations as of the maximum size.
You will need a large map, 15X 15 is the stock maximum.
With that many industries and cities (I presume) the stations will run into each other.
But if you need any help just post it here, we will be glad to help.
