When installed in the great forts built pre 1914 they would be able to run up and down on their tracks (which would be installed in a trench or protected by a concrete or stone parapet) I think when on the Western front etc they would tend to be in static positions and effectively rapidly installable pill boxes. In WW2 the Germans had a very similar device used mainly in Italy on the Gustav line but also, I think, on the Atlantic Wall and these were static when emplaced.
Hi all What you call 'Fahrpanzers' were used in limited numbers by the Danish army as well. For transportation horse carriage-wheels were fitted and horses pulled the contraption to it's destination. The Danish examples were used to beef-up defences along the defensive forts around Copenhagen. Positions were built before hand, but there was no provision for transportation along narrow gauge railway in Danish fortifications. Wether the Danish Fahrpanzers had railway wheels is not entirely clear to me. One Fahrpanzer is preserved at the Danish Armoury Museum in Copenhagen. Next time I'm passing by I will take a carefull look. Read more about the fortifications around Copenhagen here: http://www.vestvolden.dk/Nyheder_news/English_summary/englishsummary.htm
The German Fahrpanzers in WWI used at the Western front would most certainly only be transported on their own small rail wheels for very short distances. To transport a Fahrpanzer for any considerably distance it would most likely be loaded on a normal 600 mm. narrow gauge wagon. Only when reaching the operating limit of the light railways it would be unloaded and put on the very light rails that were used for the trench tramways - they were sometimes made from wood! Once emplaced in a trench the Farpanzer would probably not be moved around - and the rails (track panels) probably lifted to be used elsewhere.
I have read that trench tramways were even laid out into no-mans land to transport gas cylinders in preparation for gas attacks by the British. Usually this was done under cover of darkness, as was most of the supply runs to forward positions (rarely front line positions, though).
I have collected photos and drawings from this great site, as I hope one day to build a Fahrpanzer in 1:35 for my collection of military narrow gauge equipment.
I hope my information will come in usefull for some of you.

As shown somewhere else in this forum the Fahrpanzer had its own horse drawn carriage for transport from site to site
Even more from my archive on the Fahrpanzer. The image is downloaded from an auction site. The photo shows a Fahrpanzer during transport on 600 mm. track panels with light rails. This mode of transport would be most feasible in narrow trenches on the way to the Fahrpanzer's emplacement.
There is definitely some sort of glitch with the forum software as somehow your posting has hi jacked the file I posted over 24 hours ago - ie fahropen.jpg!
Tim: A lot seems to indicate that your recent posted photo of a Fahrpanzer captured by French forces is exactly the same as portrayed in my file Champagne 34.
