DBS shunter 294 634 (or more properly, 98 80 3294 634-1 D-DB) certainly was when I spotted her yesterday around 1 o'clock at Griesheim Station in Frankfurt:

The operator was just climbing from the cab and then onto the flatcar, in order to shunt the entire setup into a siding further in the background using his radio remote control. Note the signal in the background showing a Sh 1 aspect (the two white lights) which is a proceed aspect for shunting movements - these being treated differently from train movements under German signalling practices.
