__ The leading vehicle, therefore, also cannot be properly called a
© "waggon." It is certainly self-propelled, and so comes within
the term "motor," but the other element necessary, namely,
_"waggon," being absent, the first car is excluded from Item
380 (£). It was argued that excess of power does not deprive it
of the character of "motor waggon." I entirely agree, if, with-
out the excess, it possesses that characteristic. If, for instance,
_ the first vehicle, called for convenience "the engine car," could,
_ together with the first trailer, be considered as one vehicle, the
argument would have application, because the combination would
'include self-propulsion and a waggon. Any excess power trans-
'missible to other trailers, or, as suggested, utilized for racing
urposes, would not deprive the combination of its true character.
ut the combination aspect was expressly rejected by learned
sel, and discreetly. Unless the whole train be one unit, the
vo vehicles are separate, and have two distinct chassis.
