最近のgngoatで話題になっているのが、「datenail」です。辞書をひいても分からなかったのですが、Wikipediaで見てみたら、枕木の古さを示す表示とのことです。原文は、
Datenails were tagging devices utilized by railroads to visually identify the age of a railroad tie. Different railroads used different sized nails with either alpha or numerical markings. An example would be a Southern Pacific Railroad nail with the marking "01" stamped on the head of the nail. The "01" would identify the nail as being hammered into a railroad tie in the year 1901.
Datenail use has dropped dramatically since the mid-20th century and the advent of more modern maintenance of way equipment. Ties are no longer marked in this manner in North American practice, and the nails themselves are now sought after by railroadiana collectors. It should be noted that the Southern Railway never made use of datenails.
