It seems to me he wants a small route that works fine in TS2010, as simple as that.
"Muliebuck" has quite a few branchline layouts for TS2010, around 4 baseboadrs in size. There isn't alot going on, but the layouts are beautifully made, and great to merge into excisting layouts, or as a base to start your own layout from.
My Dukes Denver, 7 baseboards, all built-in content (so no need for any downloads), representing a British light railway might be of interest. It was built for TRS2004 but I have imported it into both 2009 and 2010 without problems. Kuid 275817:102393. 883 downloads to date. Easy to customise using any desired content, and to extend (both of which I am doing at the moment).
To add to this I can say only 5 kuids are missing, or need to be changed in ts2010. If I needed to hunt for others I can't remember.:hehe:
Two, <kuid2:30671:27367:1> and <kuid2:30671:27382:1>, are Protolars industries, PL_Food and PL_Warehouse respectively. Those are superseeded by the two build in combined ones in 2010 I think.
The other three are dependencies for US&S type B Home/Distant semaphore kuid numbers 39730:60000 to 60002. These are probably corona's I expect.
