Talk:SR N15X class

Hybrids?
I have some problems with this article, especially the sentence in the first paragraph: "The final design was based upon that of the N15 Class locomotives, creating a hybrid locomotive that was created out of several standardised parts". Starting with the last point, what standardised parts are we talking about? The cab - the tender? What were they supposed to use? When you convert a tank into a tender engine you have to supply the missing parts from somewhere; you will sure avoid wasting time and money on new design. 2) In this respect, can we consider the U and U1 classes as "hybrids" because they were based on rebuilds from tank engines? 3) In what sense were these engines based on the N15? It seems pretty evident that they were so classified because it was hoped that they fit into the same slot. 4) As for the King Arthur front end, in the case of this locomotive it was an update on older Urie versions; it was therefore only natural that they would try this improvement on the N15X. I would also be interested in knowing the importance of the Sevenoaks derailment in the decision taken to convert the Baltics. A final nit-pick: is it valid to call this a "rebuild"? The locomotive was very little changed materially - and the improved front end could just as well have been applied to the Baltics. One more thing - IMO the label "unsuccessful" (like failure) is attached with a little too much relish by many writers.--John of Paris (talk) 15:40, 12 December 2007 (UTC)

Holcroft - Bad References
Holcroft wrote Locomotive Adventure Vol1 and Vol2. Locomotive Panorama Vol 1 & 2 was written by E.S Cox. Its probably more likely that the Holcroft volumes are intended, but should be checked before altering. It could, of course, be a melange of references from both sources. 212.159.44.170 (talk) 14:55, 9 June 2016 (UTC)
 * The N15x class is not mentioned in either volume of Cox's Locomotive Panorama (Cox hardly touches any Southern Railway classes at all), so I'm pretty sure that it will be Holcroft's Locomotive Adventure; but I only have vol. 2, which does not mention the N15x class. -- Red rose64 (talk) 15:14, 9 June 2016 (UTC)
