I briefly mentioned this in a post elsewhere in the forum, but just to let everyone know (especially you, Steve) there will be a Lake Superior & Ishpeming (MLT Michigan Iron Ore) AG4 template coming as soon as I wrap up work on the eastbound (the westbound is in the can). At first I didn't think I could do much more than MLT did with the activities other than to add a bit of random switching, but using AG4 combined with Bin I've managed create prototypical (well, almost) turns and add more AI traffic (not a lot, but enough to make it look like the railroad is actually earning its keep). There won't be any extra rolling stock downloads required -- all you'll need is the route itself, AG4, and the latest stable Bin patch release. Hopefully I can get it tested and uploaded with a week, two at the most.
