I fired up RRT2 for the first time in ages last night. I have the Steam Platinum version. I was reading through the manual and it mentions the earliest start being 1804, but I can't seem to find any scenarios or campaign mission that starts earlier than 1830 (I know the real early trains are terrible but I have a weird fondness for them). Am I missing something or is there no way to play that early?
