[edit] Naming convention
There is a discussion about the naming convention to use for articles about British locomotive and multiple unit classes at Wikipedia talk:Naming conventions (British railway locomotive and multiple unit classes). Your comments are more than welcome. Thryduulf 22:23, 21 Mar 2005 (UTC)
[edit] Power
In the variants table, the figures of approximately 50 tons were first posted without saying what they were, then later converted to kN, then labeled "power", which does not make sense-that much tractive effort on a loco this size would be useless as the wheels would slip. I have relabeled them "weight", which makes sense and is consistent with the other table.
I have also removed the 350hp/260kW power figure as I doubt its correctness: I have seen both 400hp (eg. here) and 350hp quoted. It appears most likely that early versions were 350hp and the final standard 08 400hp, but I have yet to verify this, and I do not know whether any 350hp versions were actually classified 08 (rather than 11).--QuantumEngineer 11:55, 4 December 2006 (UTC)

In Ian Allan ABC of British Railways Locomotives (winter 1962/3 edition) entry for D3000-D3116 shows 350 bhp at 630 rpm and for D3127 onwards shows 350 bhp at 680 rpm. My guess is that the uprating to 400 bhp took place at the same time as the 50 rpm speed increase and that the entry for D3127 onwards should read 400 bhp at 680 rpm. Can anyone confirm this?

- Does anyone know the difference between the 6K and 6KT engines? I thought the 6K had a massive crankcase for stationary work while the 6KT had a lighter crankcase for railway work but this [2] suggests otherwise. Does anyone have more information? Biscuittin (talk) 20:24, 10 February 2008 (UTC)

- It's the same engine. E-E made a basic in-line engine called the 'K', and the traction version was a 'KT'. The only difference would be the feet and mountings for the alternator. A marine would be a 'KM', a marine generator 'KZ' and so on. It's the ancestor of the 'RK' ('Replacement K') fitted to later classes such as Class 56.

- Incidentally, E-E/Ruston engines were also sometimes prone to the 'accountancy rebuild' syndrome. After the 'K' and 'V' engines had finished their production runs; if an engine had well and truly mangled itself, it would often be 'rebuilt' by simply holding the identity plate in one hand and screwing a new engine on to it when the accountants weren't looking. Several class 40s and 50s probably ended their days with derated 16RK3CTs, so I wouldn't be surprised if quite a few 08s actually carried 6RKTs at the end. ChrisRed (talk) 12:44, 8 April 2008 (UTC)

therailwaycentre.com gives Class 11 (12033-12138) and 12 (15211-15236): EE 6KT 350hp (194hp at rail) Class 08 (13000-13366, D3000-D4192, 08 077-08 958) and 09: EE 6KT 400hp (260hp at rail) Class 13 (D4500-D4502, 13 001-13 003): 2xEE 6K 350hp each The TOPS number range given for the 08 might be taken to suggest that 08 001-08 076 (which did exist, at least 2 of them still do) were different, though one might expect that were this the case they would have been assigned a separate subclass. The 13 and D number ranges for the 08 overlap with the ranges they give for D3/3, D3/5 and 10 (non-EE 350hp engines).
Fragonset (website no longer available, probably because they have gone bust), who might be expected to know since they owned 3, gave 400hp at 680rpm...and, on the same page without explanation, 350hp.--QuantumEngineer (talk) 19:54, 15 March 2008 (UTC)
