Under the [[Whyte notation]] for the classification of [[steam locomotive]]s, '''4-4-4''' represents the [[wheel arrangement]] of four [[leading wheel]]s on two axles, four powered and coupled [[driving wheel]]s on two axles, and four [[trailing wheel]]s on two axles.  In the United States, this arrangement was named the ''Reading'' type, since the [[Philadelphia and Reading Railroad]] was the first to use it.  In [[Canada]], this type is known as the ''Jubilee''.
