The double-decked MCi railmotor (German: Dampftriebwagen MCi) was built in 1882 by Krauss and Company with the works number 1181 and delivered to the Royal Bavarian State Railways, who deployed it in the areas of Würzburg and Bamberg.

The steam-powered railbus had a B'2' wheel arrangement, one axle pair being driven by connecting rods.

It had a transverse boiler and a gross service weight of 28 tonnes.

Its Stephenson valve gear and brakes were accessible at both ends.

The vehicle was a one-off and was only in service for a short time.
