Urban Games has a fever for more train bell, so they are now offering Train Fever on Steam, a new railroading simulation for Windows, OS X, and Linux. There are details and a launch trailer on the Train Fever website, and here's word on the game:

Implementing lessons learned from the genre’s rich history, Urban Games have developed a state-of-the-art railway-simulation inspired by the likes of 1994’s Transport Tycoon. Using an in-house engine built specifically for the game, the team poured their affection and knowledge of the genre into Train Fever, combined with a desire to add the kinds of features they always wanted to see themselves, to create a train sim to be reckoned with.

Train Fever delivers an advanced railroad business simulation set against a backdrop of sophisticated randomly generated 3D environments and lovingly crafted models. Players can step back to the golden years of the industrial revolution with steam trains dating from the 1840’s, or fast forward to the powerful locomotives and sprawling cities of the modern day. Establish a transport company, build infrastructure, buy rolling stock, manage the lines and watch the world evolve dynamically as the steel-wheeled empire flourishes.
