Version three of the IIR has just been released in the file library here at RWA.
I know back when v2 came out I said this would be the "final version", but there were some issues with v2 that still needed fixing (signaling, missing grade crossings), so I did a little update and expanded the route for another few miles while I was at it. V3 now also has a little harbor, where Captain Bazza's beautiful ships are docked, and the engineer (you!) can do a lot more switching of warehouses, coal and grain docks, and another small yard.
Also, as far as I know all old scenarios, including the ones by Doug Smith (see here: http://www.smittyslocomotiveshed.com/ ) still work without a problem.



Cheers,
Michael
