I have created a successful activity from the Sandpatch64EB Template. I assume I can create another activity using the Sandpatch64WB Template????

Also could someone give an idea what the .pro (extension) and .csv (extension) are used for.
Thanks and regards.

You can create as many activities with each template as you wish, as long as you name them differently.

Don't mess with the .pro and .csv files. The .pro files establish which local regions are reached by each path and the order of reaching those regions. The SWLACT*.csv files establish what rail cars are available in the template and the places where pick up and set out events can take place. The SWLTDB*.csv files establish which tracks are part of each region, what type and how many rail cars are available for pick up and/or set out at each track, plus defining certain special functions of the tracks.

I suggest that you should not mess with these files.

Thanks for your advice. I will follow it carefully.
Regards,
Fred
