"If WW2 hadn't happened" is worth a thread in it's own right.

All of this information about power output and weight and electric motors is genuinely fascinating, but I just wish I understood more of it! Physics A level will only take you so far before you start to regret the humanities degree.

Although I agree with whats been said here i am almost  in agreeance with what happened , Through fate I was allowed to see the last "glory" days of steam as well as witnessing the early transition to diesels.................guess I was lucky

Some other nationalist idiot would have taken Hitler's place, and we might have been worse off, because that idiot might have listened to his generals rather than throw tantrums.

Mind you, we could have thousands of those threads; going back to "what if the Moon hadn't happened by, many billions of years ago?"

So to recap and probably start a few arguments,  the actual pilot scheme locos were;

 

Type 1

 

BTH x10 (class 15)  D8200-09  (with another 34 ordered later)  all gone by 1971

NBL x10 (class 16)  D8400-09 all gone in 68

EE  x20  (class 20)  D8000-19  (with 108 as follow on orders, then another 100 to replace Claytons)

 

 

 

Type 2

 

NBL x10 (class 21) D6100-09 (with another 48)  all gone by 71 (68 for locos not rebuilt as 29)

NBL x6 (class 22) D6300-5 (with another 52) all gone by 72

EE x10 (class 23) D5900-09    all gone by 75 (71 in revenue service)

BR/Sulzer  x20 (class 24) D5000-19  (with another 131 24s and 327 25s) all gone 1987

BRCW x20 (Class 26) D5300-19 (with another 26 26's, and 69 27's) all gone 1993

MV x20 (class 28) D5700-19 all gone from service by 68

Brush x20 (class 31/0) D5500-19 (and 243 31/1) just about clinging on in service?

 

Type 4

 

EE x10 (class 40) D200-09 (with another 190) lasting till 85

NBL x5 (class 41) D600-05 lasting till 67

BR/Sulzer (class 44) D1-10 and 127 45's lasting till 1989

 

As most of the locos built after the pilot scheme orders were slightly different I've included 45s with 44s and 27s with 26s etc. 

 

Looking at production dates it would make sense to include the BR built Warships D800-802 but although built as a pilot they weren't part of the pilot scheme according to my limited research on Wiki.  Realistically they worked alongside the D600s and showed rather clearly which was better.

 

I did see the comment that the 30/31 was too heavy to be accepted as a Type 2 but they did order 243 more so they can't have been that upset (until the engines broke).

 

 

So if we consider success to be most of the production locos managing 30 years in service with original engines then the only success stories are the 20 and 26 although the 45 is very close.

IIRC the booked life of a loco was 20 years to pay off its costs. To the list above you have to differentate between those locos withdrawn early due to unreliability and those withdrawn due to either non standard or the work they were intended for disappearing. Also, you need to count different classes together, the 27 were a later version of the 26, but using uprated engine and a different supplier for the electrics due to the problems with CP, the same can be said of the 45 and 46s. The rats almost made book life, but the work they were intended for had gone. The 15s were another class who were reliable but went because they were non standard. The same can be said of the 29s. 

 

The standardisation of BRs loco fleet came down to either EE engines or Sulzer. Everything else went.
