I can offer three small routes on the Download Station under my KUID 275817 (built for TRS2004 but I have imported them to TS2010):
RM1156 UK 1 baseboard, TRS2004 built-in content only.
RM1156 France 1 baseboard, developed from the above with a French ambiance.
(The names because they are based on a layout suggestion in Railway Modeller November 1956 - shows my age!)
Dukes Denver 7 baseboards, TRS2004 built-in content only, a UK light railway inspired by the Colonel Stephens lines.
Although country specific, all can be adapted for use elsewhere - I have done it. Incidentally, I am now updating Dukes Denver (which seems to have proved modestly popular) to take advantage of the benefits of TS2010.
