My old national Geographic map shows a narrow gage railroad running from Tunis south to Gabes or Sfax. Its not clear which is the actual terminus.

Since supply is the foundation ofthe offence this railroad would be important to the Allied effort to capture Tripoli. So, was there in fact a railroad from Tunis to the Gabes/Sfax region, and what gage was it?

Also are there any sources showng the location and nature of the airfields in Tunisia and Lybia?
