Nose doors on F units - some as do, some as don't - Model Railroader Magazine

     Never seen an AS BUILT F-unit, from FT-103 to FL-9 2059 that did not have a nose door.  Some of these "executive" F's of the post F-unit era have had their nose doors sealed, along with the addition of HEP, ditch lights, etc, but not original construction.
