             Activities are also useful in providing tutorials to help you get the most out of Open Rails.
             See Australia's Zig-Zag Railway for <a href="http://www.zigzag.coalstonewcastle.com.au/">some very effective steam-based tutorials</a>.

             A great place to start would be the free Siskiyou Route from the USA. The creator, Dale Rickert, has assembled <a href="http://www.siskurail.org/news.php">a package of instructions, examples
             and even videos</a> to show how to create both simple and demanding activities.

+            Peter Murdock and Dan Reid have collaborated over a set of activities with a tutorial to help people "get started" with shunting activities 
+            in Open Rails. 
+          </p><p>
+            The activities are based on the free BNSF Scenic Route currently being offered by TrainSimulations (<a href="/">see our homepage</a>). 
+            There's a version for the route prior to 20-Oct-2020 and another for the more recent route. You can find them by searching the 
+            "Open Rails - Open Rails Activities" section of the <a href="https://www.trainsim.com/vbts/tslib.php?do=displaysearch">TrainSim.com Library</a>

+            Peter Newell has provided <a href="http://www.coalstonewcastle.com.au/physics/demo-activity/">13 simple activities</a>
