JB,
Which is how it works as a primer!

Richard,
You need good metal cleaner to get rid of all surface oils. Stainless steel cleaners such as Bar Keeper's Friend work well.

Thanks for the info regarding the blackening agent gents.
I decided to go with the U-Pol etch 8 primer, and a full respray. (Apart from the engine room roof doors and panels, as the paint was totally sound there.)
Deja vue !!

These are probably of no help whatsoever but........

I'm currently scanning and post processing another load of photos and coincidentally came across these photos of a Class 47 at Rocket 150 at Rainhill on 24th May 1980. (Dunno whether he'll remember but I was there with Steph and both grand fathers). However, as it's 47 581 and named "Great Eastern" I'll take a guess that it's a Stratford loco with light grey roof. Nevertheless, it's good to see a loco in mint condition. Note also the view through the engine room window.

One other top tip for safe masking tape removal is to thoroughly warm the model with a hair dryer.
When pulling the tape off avoid pulling it at 90 degrees to the side, instead pull it right back on itself so the unstuck side being removed slides along the body as it comes off. This can help too.

Further to the discussions about blue roof or grey roof here are another couple of photos taken at the same time as the 47 above. The 55 clearly has a blue roof. However the 56 equally clearly has a grey one and I'll be pretty certain it won't be a Stratford loco!

Does this indicate that whether the roof is body colour or grey depends on the works which last outshopped the loco, or maybe in 1980 we're in a transition period before everything was painted with body coloured roof?

(The photo of the 55 has been post processed, the 56 has not as it needs to be rescanned).

You are using the wrong masking tape, get some Tamiya masking tape it works great and won't pull the paint off.

Its easily available from model shops or on the web and comes in varius sizes such as 6mm, 10mm, 18mm, and I think a 40mm one too.

Oh, I remember, possibly my first contact with a production Deltic. Definitely my first 56...

And having just passed a Deltic's worth of postings (3300) maybe a significant post. Or maybe I just need to stay in more...

Hi Richard,
I had used Tamiya on the warning panel edges. I had even de-tacked it!
I think where I screwed up (let's face it it was MY fault ) there was a little primer showing through, so I applied a little more blue celly. By now the rest of the loco paint was rock hard, I just forgot (old age) I had applied the additional coat below the window.
What I do love about this paint though, (when it sticks) is how it polishes up with 1500 grit and is as smooth as glass and very hard.
When you apply the weathering the paint stays put when you are applying enamel thinners etc.

Mine was at the Didcot railway centre probably over 25 years ago. It was running on one engine and it felt like an earth quake when it passed!!:)

Brian, that 56 roof is blue, it's just not clean like the Deltic.

There are only two colours for blue diesel era roof's, blue or 'Stratford' light grey. Any other sort of grey or black will be dirt as the roof's never got washed in washing plants, the exhaust dirt is a oily sticky grubby mess which tends to stick to anything and leave a matt finish, and that's the best clue; as far as I know, BR never painted matt colours so if you see a matt colour then it's not factory applied ;).

As far as I know, there are no exceptions to this rule until the mid 80's when sectorization came into force.

And, yes #581 is a Stratford based loco, interestingly the buffers and couplings are silver, not grey, you can just make out the slight tonal change. Wheel rims and bogie pipe work is white.

All the best

Didn't refurb Class 50s have grey roofs?

They wouldn't have been Stratford-based locos!

Steph
They did, that's why I wrote 'Stratford' highlighted as a general term, the grey roof was applied to later locos but not in pure BR blue colours, only Stratford applied their grey roof's to BR blue locos, the others (as far as I know) were all applied to 'Large Logo' locos which I thought was not classified as true BR blue era engines.

56 084 was the first large logo loco with a grey roof and was out shopped from Doncaster in Oct 1980, somebody must have thought it fitting as the class 50 followed soon after in 81. Stratford changed the large logo format by not applying full yellow cab sides, simply added the black windscreen surrounds to their already grey roof engines and applied the large logo...some but not all.

The only non Large Logo engines with grey roofs that I can think of at short notice are two 33's #025 & 086, which had grey roofs applied when they were named in 1980 and a couple of 73's but these soon had full yellow ends and large logos added I think. 1980/81 is a real mix of schemes, some only lasting months, very hard to keep track of all them.

For me, Large Logo is the end of the pure BR blue period and along with Red Stripe Railfreight, the beginning of the transition to sectorization.

It was around 1980 that BR relaxed depot painting, as well as engine naming, Stratford and Finsbury Park had been bucking the trend for a short while before that, sadly when the last Deltics were transferred from FP to York the first thing York did was paint the white cab surrounds back to blue.

All the best

Brian,

Your right 036 was the first one done (too much Micky flippin Mouse to think straight LOL) way back in 78 and I think I have a poor B&W image of her on a fly ash train at Peterborough around 79/80 somewhere, 56 084 was the first loco built straight into large logo livery.

I think we might need to set up another thread if this continues - we're mighty close to hi-jacking this one.

However Mick, and I have absolutely no knowledge at first hand, nor any historic interest, so my comments are based only on what I see, and that is the roof of the 56 in a lighter grey than exhaust fumes and oil would be and also an amazingly well defined demarcation between the bodyside blue and the roof grey. The roof is also reflective over the cab suggesting that this has been cleaned to a gloss finish. In the same series of photos I have some of a couple of Class 25s, also at the S & D 150 shindig. One of them certainly appears to have a blue roof with a very approximate and soft demarcation between the blue and exhaust/dirt and I'd have thought this to be consistent with automatic cleaning. Also nearly all the locos and vehicles were specially "bulled up" for the occasion with cleaned roofs - in fact the loco with the dirty roof was the exception, and the other shows clear evidence of exhaust staining around certain roof apertures.

All in all I bow to your certain knowledge but wonder whether there might be exceptions. In the case of 56036 above the demarcation body to roof matches that on "my" 56.
