Apparently \centering applies to the lines of a paragraph, but not to  
boxes found outside of horizontal mode. \XeTeXpicfile does not by  
itself cause TeX to leave "vertical mode" and begin paragraph building.

You could fix this by putting \hskip0pt before \XeTeXpicfile; that  
will ensure TeX enters horizontal mode, and the picture becomes part  
of a line that will be centered (rather than just a box in the  
vertical list).

However, I'd suggest you simply use \includegraphics instead; with  
\usepackage{graphicx} in your preamble, this should work as you want  
(and is more readily portable to non-xetex usage):

   \begin{figure}[htp]
   \centering
   \includegraphics[width=10cm]{img/maerklin-schienentypen-h0.jpg}
   \caption{Gleistypen}
   \label{fig:gleistypen}
   \end{figure}
