[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)
- Most of your queries are now covered in the article. Regarding the final one (and your picture), the answer is "yes"! This is an example of double-heading. The two diesel-electrics are working in multiple and are therefore effectively a single (articulated) locomotive until such time as they are disconnected again. Coupled in front of the steam locomotive, which must have its own crew, constitutes double-heading. If the two diesel-electrics were NOT working in multiple, but each had their own crew, then this would be an example of triple-heading. Timothy Titus Talk To TT 04:11, 17 April 2008 (UTC)
