wehrpass help

[AndyD]

Hello! could anybody out there help with a translation for me?I have obtained a wehrpass in which the stamps read:feldeisenbahnbetriebsabteilung18.What unit is this,i think it has something to do with railways?Also i wondered what rank a sonderfuhrer was,as there is an entry dated 15/4/41 which reads:Beliehen als sonderfuhrer noch shellengruppe G.
And finally!(for now!)The medical and fitness entries section on page 5 is totally blank,is this unusual? and if so any ideas as to why it may have been left blank?
Hope someone can help!
Kind regards,
yorkie

The "field railways" unit entry sounds Imperial. A Betriebs office was responsible for routing and scheduling trains.

The second entry is probably something Verliehen (awarded) as a Sonderfu"hrer in "Stellengruppe" G-- the category of specialist (whatever it was).

I suggest that this man was, probably, a WW I vet so his medical category was not important as his position was attended more by his knowledge than his physicla attitude so his page 5 was blank as he was in this position or something similar before this system was put in use. Sonderfuhrers were specialist in the army with an equivalent rank to the active troops, the Sondefuhrer G group has the equivalence to a Gefreiters, they are usually civilians with special knowledge who were given special treatment, here could be a railway worker who's expierence gained him this recognition.
