The Update 1.13 and a new (paid) DLC "Down under" for the railroad-management-game Railway Empire is now available for Linux on GOG and Steam.

Description DLC:

New scenario: “Pioneering spirit” (1830-1930)
Map expansion: “Down Under” (available in Free Game and Sandbox modes)
3 new historical engines: Heisler (0-8-0), C30 (4-6-0) and Class S (4-6-2)
New tradeable goods (eg. seafood, Rail-O-Mite and canned beer) and 52 new cities to discover
New music tracks, reworked city buildings and unique mission structures (eg. Sydney Harbour Bridge)
New Settlement feature unique to the “Down Under” map: on pre-determined locations, players can now establish new cities and this way arrange the economic system to their liking

During the first half of the 19th Century, the colonial territories of Australia are sparsely populated and consist primarily of coastal cities and a few smaller farming settlements in the remote outback. However, a series of events is set to spark an industrial revolution, one that will usher in an era of change for Australia and secure a lucrative future. In the Railway Empire “Down Under” DLC, it is up to you to tame the unforgiving outback and expand your railway network across its wild terrain and beyond. Your railway will ultimately be the key to laying the foundations for flourishing cities and to connecting remote mining settlements to coastal metropolises. Are you ready to face the sun-scorched landscape of Australia’s Red Centre?

In addition to the new challenge map, in this update, we’ve used the community’s vital feedback to focus on tackling the below points, alongside adding many small improvements in the code, too small and numerous to list, mostly in preparation for the latest DLC release ‘Down Under’:

New addition

New Challenge Map ‘Thunder Across the prairie’
Thousands of miles of open prairie to conquer, your clients are breathing down your neck with a busy schedule and on top of it all, speculators have driven up property prices. Make your way through the diverse landscapes of North America, connect the coastal cities and create a railroad empire from scratch. Building a transcontinental railroad is no walk in the park, but if you can’t do it, who else can do it?
