A rail vehicle includes a milling device for finishing the running surface of track rails during the travel of the rail vehicle along the track rails. The rail vehicle has a chassis frame having wheel sets. The milling device is provided with a milling head, and includes a framework arranged on the chassis frame having a milling head receptacle, which is displaceable vertically and transversely in relation thereto. The milling head receptacle can be supported for the vertical guiding via a guide shoe on the running surface and for transverse guiding in parallel to the milling head shaft via a guide stop laterally on the railhead. The milling head receptacle forms a transverse carriage, which supports the guide shoe and the guide stop, and the guide path of which, which is vertically displaceable, is provided on the side of the milling head receptacle facing toward the guide shoe.

A method and apparatus for the refurbishment and repowering of wind turbines through the extension of existing installed blades so that they can catch more wind energy and therefore enable an increase in the overall average power output of the wind turbine.
