There's a lot to do!

New modules need to be tested to insure that their trackwork aligns properly and that trains can safely traverse them.  The wiring is tested, too.  It is best to do this testing before ballasting track and adding scenery, just in case...

Members also help one another with tasks.  Some folks are better ballasters, some better at trees, some at wiring, and so on.  Trading these tasks, or even just a little tutoring, helps everyone make progress with their module.
