I have decided that I may draw up plans for a set of etches to allow me to convert a DJ 71 into a 74. I was thinking of two approaches:

  1. a set of three etches: two sides and a roof
  2. two etches, one that has the roof and sides on it to be wrapped around the shell and a second that as the raised roof panels etc.

 

What would be your thoughts as to the best approach? I am tending towards the latter option.

 

I would have though very difficult to make a one piece wrapper fit snuggly? Whereas you can trim to fit and fill gaps with separate panels.

Getting a wrap-round etch to align properly all round could become a serious issue. Whereas the 3 part etches could each be adjusted for alignment before the glue goes off

I was also going to draft the fuel tank sides etc.

 

To help me, does anybody know of any good side-on views of 74s and/or accurate general assembly drawings? I have done quite a bit of searching but have never found a good side on view, photos always seem to be at an angle which, whilst not ideal, may have to suffice.

 

Thanks,

Roy

 

 

This new book published by Pen & Sword has several photos of class 74s, including a couple that are side on shots and would probably be good for your needs.  Unfortunately though both photos are of the same side, the one without the large bodyside grills.  A good starting point, I hope nonetheless.

ISBN 978 1 52672 061 0

 

One very slight word of caution about this book, if from the title prospective buyers are expecting it to include electric units, it doesn't.  The 'Units' in the title refers to the various BR(S) DEMUs.  My copy only arrived this week so I've not yet had a chance to have a thorough look through, but it does look promising.

 

As far as GA drawings are concerned, British Rail Main-Line Diesels (ISBN 0 7110 0617 2), published by Ian Allan and long out of print, but probably available secondhand, is a good starting point.  All the drawings in this book are to 4mm:1ft scale.  The drawings of class 74 are on pages 62 and 63.

Thanks for that. I hadn't considered British Rail Main-Line Diesels as I have an early copy with drawings by R S Carter that I know are generally thought to be inaccurate. It looks as though the version you quote isn't the same and that the drawings may be new.

 

I will have to order copies of both books.

 

In the meantime, I have bought a couple of black and white photos that, although at a slight angle, are proving very useful for laying out the sides drawings.

 

Thanks for your help,

Roy

The loco in the photo looks to be 73102. But not sure about the wagons behind her. Are they PCA V-tanks?

But similarly, Bachmann, despite their superb foray into EMU's to date, have delayed and delayed the one unifying EMU for the suburban terminus modeller and more rural Kent, Sussex or elsewhere layouts, the 2 HAP. But they do seem to be going ahead with it, maybe next year.

 

Unless my eyes deceived me, there was an engineering prototype of one of the 2-HAP cars in the display cabinet at Kidderminster this weekend.

That is very good news - thanks! Although I seem to recall they had a version of it on display some months back, but the delivery date kept slipping nonetheless, into 2020. But let's hope the model you saw was a further development. :imsohappy:

It was on show at Kernow’s Guildford shop opening. Look very nice.

If I remember correctly (and that's a pretty big if), there's a good side on shot of a 74 at Clapham Junction in one of Michael Welch's Southern based albums from Capital.

Modern Locomotives Illustrated #198 dedicated to the electro diesels has a decent section for the 74s, with drawings (Graham Fenn) and some good photos - but none are side-on.

Yes, caption says 73102 but is silent on the type of wagons.

Several good side on and useful three-quarter photos in The Power of the Electro Diesels, by Colin Marsden, published in 1980 by Oxford Publishing.

Possibly the Rugby Cement STS tanks, produced as a recent model. There was a regular Halling (Kent)-Southampton area working of them with a 73.

The train in the photograph is 6Y80, the 09:46 Bevois Park (Southampton Up yard) - Halling empty Rugby Cement train climbing the incline up to Battledown Flyover. It was taken from the foot crossing; with St John's Road bridge, East Oakley in the background. The load would usually be the 15 PC017C cement tanks built by Fauvet Girel in 1985 and now produced (all 15 of them) in 00 by Accurascale. However it looks like there may be a "straight barreled" PCA (diagram PC010A) on the rear, which was not unusual as there were no maintenance spares in the "French" fleet. The train was a regular turn for a 73, though 33s were not unknown.

Pictures please!

 

I don't know why I like 74s, I only ever saw two, parked up at Newport awaiting entry to Cashmores, from a passing train.  They obviously made an impact on me!

Hi

Sorry for the delay, but it took me 10 days to complete the 74. Thanks to Miles73128 and his model photos for spurring me on. Here's a couple of photos of E6103. The first show the chassis adaptions to the Hornby 71 chassis and the adaptions to the Silver Fox 74 body casting, so it fits the Hornby chassis. The longest job was making the 8 cable pockets for the cab fronts, each with a hidden plastic rod so it could be secured into place through the cab front.

Great work.  They have a rather unfortunate countenance, these locos, don't you think.  Sad and forlorn, rather like a tube-train that never sees daylight!
