Since reading the manual can be a bit of a pain for those accostumed to 18xx (oh really, each share pays 10% of what the trains run? omg), and it can be a bit difficult to find those specific rules among descriptions for newbies, I decided to make this file. Here you go. These "differences" use 1830 as the standard. Send me a message if you find any mistakes or if you think there's some important information missing.
(this is version 1.1 of the file, after some kind corrections by Ohley himself. Thanks!)
