There were no direct train services between Lithuania and Germany in the late 1800s.
Why? Lithuania was part of the Russian Empire, which used a broader rail gauge (1,520 mm) than Germany's standard gauge (1,435 mm). Cross-border rail links were minimal; travel required a gauge change at the border (e.g., via Warsaw or East Prussia) or alternative routes—boat across the Baltic, or overland through Polish territories.
Through-train service only became feasible after WWI with Lithuanian independence and gauge standardization efforts.
