Based on Avalon Hill's board game of the same name, 1830 is a railroad empire building game that is along the same lines (although a different style of gameplay) as the much more famous Railroad Tycoon.

Capturing the very look and feel of the board game, all the way to the hexagonal playing field and track tokens, 1830 is a turn based game that emphasizes the successful running of a company and manipulating the stock market rather than managing a railroad. Tracks can be laid, cities connected, trains purchased, and schedules set, but the ultimate goal in the end is making money, even at the cost of your company, you'll wind up buying and selling a number of them during the course of the game anyway.
