Handbags   (The sad, the bad and the ugly. Non-productive stuff here.)

Found some figures online.

There are currently around 1,500 steam locomotives in many series and gauges across Germany. Of these, around 1,200 can be rolled and around 300 can be operated, of which around 150 are ready for use.

I guess the original operator (Deutsche Bahn, and earlier Deutsche Bundesbahn) still running them makes a difference. (note them still having that water crane as opposed to having to fill from a fire hydrant here.)

Google says UK has 400 ex BR, and 550 ex industrial, but I don't know breakdown into rolling/working/ready as in above list.
