@Gaelan@ifrit Great! Though, maybe ReNFE should fall in your first class (*Initialism*). It stands for Red Nacional de Ferrocarriles Españoles (Spanish National Railway Network).
@ddherbon@ifrit I’m making use of a pedantic English distinction here: “initialisms” are pronounced as individual letters, while “acronyms” are pronounced as a single word
@Gaelan@ifrit Of course! How could I miss that one! XD
Just about to point out that Cuban Railways might fall in the *Locomotive* class… but, wouldn't a tag system suit better to your chart? Maybe visualizing it in a Venn diagram…?
