This scenario is the result of my discovery that there was a German armored train active during the Battle of Tannenburg in 1914, acting as a flank guard against Russian cavalry. Sadly, I could find no specific details, but there were a number of German armored trains in action almost as soon as war was declared. Presumably, this was one of them. I looked for a place where there was a flank threatened by Russian cavalry and a suitable rail line, and I made up the rest! Historically, armored trains were used on the Eastern Front for reconnaisance, support of detached infantry, and - especially - to cover retreats.
This scenario is set against the fighting around Bishofsburg on August 25th. It assumes that elements of Russian VI Corps have gotten past Bishofsburg and are moving toward Allenstein (which, of course, did not happen). Standing in their way is an infantry brigade, supported by the armored train. The goal of the Germans is to hold out against superior numbers. The Russian goal is to swarm past the Germans and open the way toward the German rear.
The table shown below is 4' x 5'. All distances are doubled for use with 25/28mm. The dotted black line is the rail track, which provides soft cover to units behind the embankment. The station - Kramerstation - provides soft cover in its wooden buildings. The hill is rough and provides soft cover, as do the woods.
Germans units aside from the armored train will set up anywhere to the west of the red dotted line. They may choose to be entrenched. The armored train will enter from the direction of Allenstein. All Russian units must move onto the table from the eastern board edge.
