Metro simulator forums

Hello!
I've seen some cool activities in the forum here and there, and they are awesome.

I want to ask that is it hard to do a activity? If someone could help me to get started with a small tutorial or something would be appreciated.

Thanks.

Start by reading this: http://sim.bemined.nl/wiki/Basic_Activity_Guide

Then open an activity, and see if you understand how it works. After that, you can begin to make something yourself.
That's how I learned it.

Tried to do a small activity but failed Can I just make a copy of one existing and make it bigger (like add more trains that it's busier than the mega)

When I make a new Activity, how do I know what time should I put in the " endtime "

To know what is the end time you must see when the train you are driving finish the road that's the end time.
