Preußische Ostbahn debuted in 2008, the second game in the Historic Railroads System series. It was later reprinted in 2011 by Queen Games as German Railways, briefly made available in 2019 in Print and Play format on the now defunct Winsome Yahoo! Group page, and was most recently reprinted as Prussian Rails by Rio Grande Games.

Preußische Ostbahn builds upon the system established in Wabash Cannonball and takes the gameplay to Germany, 1840-1870, introducing an innovative player order mechanism to the system. In addition, each railroad has a special characteristic, based upon its history:
