[edit] Double-heading vs Triple Heading?

Just for clarification purposes, if double-heading is stricly defined as two separate crews driving two (or more) locomotives, and if multiple unit operation is defined in Wikipedia as multiple carriages (as distinct from locomotives) with separate motors in each carriage, what would be the correct definition of a lash-up of two or more diesel-electric or electric locomotives driven by the one crew?

Would the use of three steam locomotives (with separate crews) constitute double heading, or "triple heading"?

As a further curly question - would this train (in which two diesel electrics in multiple unit operation lead a steam locomotive) be described as double heading? Zzrbiker 07:46, 8 September 2006 (UTC)
