High Iron [Alpha]

Serve waybills and hear the rolling thunder out on the high iron! High Iron is a realistic North American train simulator that encourages you to play your own way! Choose from our unique selection of locomotives and rolling stock to assemble your own train and ride the rails! Cruise down the mainline, stop at stations, switch cars at industries, and more! This game is in early development and is paid access as a result, but will be free-to-play down the line! You may experience bugs or find incomplete features during this stage of production. In its current form, High Iron is a free-roam sandbox game, but will later feature a currency system and objectives that can be completed to earn rewards and collect new trains! Developing such features takes time, and we do not have a consistent update schedule, so please be patient while waiting for new content.

Each stem is one shipped update, as tall as the gap it closed — how long the previous build stayed current. The scale is logarithmic so one quiet month doesn’t flatten a year of daily shipping. Behind the stems is the same 90d player curve, so a build can be read against what it shipped into.
