List of Württemberg locomotives and railbuses

This list covers the locomotives and railbuses operated by the Royal Württemberg State Railways (Königlich Württembergische Staats-Eisenbahnen), the national railway company of Württemberg, a state in southwest Germany that was part of the German Empire.

The scheme proved to be unworkable in practice, so in 1858 a new system was introduced as follows: In several cases the previous classes were simply redesignated.

From that time onwards, newly procured locomotives in each class were given a special group of numbers, generally one hundred, beginning at 401.

On rebuilding, locomotives were organised into new classes, but the individual locos each retained their old operating numbers.

The Württemberg metre gauge locomotives were built specifically for the Nagold-Altensteig route.
