I saw the cab at Doncaster and it certainly looks like this will be the kit to go with, certainly body wise, for shape and ease of build. But I think the MMP underframe might still just have the edge for fidelity but that's simply down to the medium being used. I've not seen the JLTRT underframe in the flesh but I reckon it won't take much to fine detail it.

I'm certainly planning to pick one up at Telford, early BR(E) Finsbury Park engine, D1500-1510 or LMR Crewe based (sans Sereck radiator shutters). I've got an MMP shelf queen class 57 and might transpose parts of the bogies from that, or certainly investigate swapping parts over. Most diesels I can gloss over minutia, but class 40, 47 and Deltics, afraid not ;)

I also saw the Brush 4 cab at Donny, do you know if it was cast in the resin which is used for the kit, as it was quit heavy, I thought that may have been an engineering sample produced just to show what the cab will look like.

Ive not got an JLTRT products, but items from other manufacturers which are resin cast seem much lighter in weight

When I visit the JLTRT stand it was too busy to ask.

Some nice details there, especially like the dropped engine room floor and beams supporting the under slung tanks.

Good to see some progress.

A little detail niggle, they've got Crewe buffer beam "bumps" covering the end of the frames I think, with Loughborough style single piece rain strip on the cab front. Still, it's easy to fill between the two bumps I guess and/or file a gap on the rain strip.

For someone like me can you please show me what your talking about.

Thanks,

I'll try. If I can borrow a picture from Compton castle off page 10 of this thread, the red boxes show the buffer beam "bumps", and the blue box where the differences on the rain strips above the front cab windows can be seen

And then by linking to a few examples from Flickr

47199 was Crewe built, in 1965, and it has a gap in the rain string, a the twin "bumps" over the frame ends:

whereas 47319, was Brush built, in 1964, as a single rain strip, and a single cover over the frame ends:

Once the buffer beam cowl was removed, so where the covers:

Have you a photo to illustrate the alternatives to the details which are highlighted in the picture?

Sorry yes, I posted my previous message to early.

edit: Also not the rear marker light orientation, vertical hinges on the Crewe built example, horizontal on the Brush one. But as that's a casting, I'm hoping you can just put it in the hole the right way.

Although this list is biased towards my modelling period (1983 - so missing things like radiator type), here's the things I've been looking out for on Class 47's:
  • Boiler / Boiler Vent
  • Marker Lights
  • Boiler Tanks
  • Royal Train Jumper (or at least the hole)
  • Electrical Cubicle Vent (Monty Wells mentions this, but it's hard to find any proof, as it's on the roof)
  • Manufacturer Plates (or evidence of)
  • Wipers
  • Frame covers (AKA Buffer Beam Bumps)
  • ETH Cables (including position)
  • Slow Speed Control
  • Rear Marker light hinges
  • Windscreen rain strip
This has come from either the MRJ article by Monty Wells, Class 47:50 Years of Locomotive History, Class 47 Diesels by Taylor/Thornley/Hill, or various 47401 Project Datafiles.

The rain strip on all class 47 is one strip continous strip across the top of the cab front. The two strips underneath often called eyebrows are down to the fabricated curve of the cab front steel work. Above the brow is curved to match the roof, below the brow is flat to accept the windscreen fixings. The bit that changed was the vertical riser between the two flat plates. On one batch the flat windscreen plates meet in the middle to firm a shallow crease which makes the eyebrows meet. The other batch have the flat screen steelwork stopping a few inches short and a curved bridging strip fitted and the brows have a gap. However even some of those when viewed close up still have a small step in the platework.

Buffer beam, those covers are not the ends of the frames, the frame ends stop behind the buffers and form part of the main frame structure. The covers are for brackets that hold the top of the buffer beam shroud and cab front to the buffer beam, on one batch two covers were used on the other just one large one but still two brackets underneath as I understand.

I have some detail photos somewhere of these areas as I researched it all for the MMP 57 a few years back.

The best way to see the frame ends and base structure of a 47 is to look at crash damage engines in workshops with no cabs or cab fronts fitted, the way the floor drops and tapers to form the drag box and front end us quite clever as are the crash posts beside each seat to protect the crew. Whilst the cab floor is flat the underlying chassis floor is nor and drops down to the buffer beam and you can see the sides and lower edge below the cab as the whole area drops down.

Hope that helps

No problems, one thing I find with books, especially those written around the eighties, is that they all tend to use the same blurb, so any innocent mistake gets perpetuated many times over and becomes fable.

Books are very good but no real substitute for getting down in the dirt and crawling over the real thing, if it still exists if course, easier for modern image modellers less so the further back in time you go.

Richard,

Best I can do from my stock.

Image1.jpg

The buffer beam and frame end beam box section is below the weld line you can see, the bit above is a simple plate filler between the cab base and buffer beam top and the bracket holds all three together. This engine has been modified with an extra fillet to support the cab step fitted at a later date.
