Not only is it a different loco it is a different gauge, this is the loco class that works the 750 lines. Many of these are located round Dresden but a few work on Rasender Roland on the Isle of Sachen. Stockers will be saving up for one of these once he knows it is about.
John, you are absolutely right - we talk here about two totally different locos. Have a look on the technical data:
