    The next unexpected difficulty with the 60 Class has been the quality of the tender castings. I would stress though that this is a rather early DJH kit and not one of their current productions. The problem? Well, there are several. The holes for the tender wheel axle ends are different sizes and depths but the worst thing is that one tender side is about 2mm longer than the other (and, in this kit, the tender side and underframe are one single casting rather than two). When I assembled it with the back square, the front was at an angle, as were the wheels. Looked at from above (or beneath) the tender was not a rectangular shape, it was more like a trapezium. As for the wheels, aside from being at an angle to the track, there was so much slop that all but one pair of wheels fell out when the tender wobbled its way along the track.

    The solution? I happened to have a rigid wheelbase tender underframe kit from Caley Coaches for the exact wheelbase of the 60 Class tender - something I bought a few years ago for a project that didn't eventuate, but is now going to prove useful. I have folded the brass into shape and soldered it together, but still have to fit the wheels and bearings and work out the best way of fitting the assembly to the DJH tender.

    I will concentrate on the tender for the moment, I think.

    Incidentally, the LMS liveried Cardean class looks particularly impressive when hauling a rake of Trix Twin "Scale Length" LMS coaches, which are fully lined out in the early LMS style rather than the simple lining applied to the Dublo LMS coaches in the photograph I posted earlier. Once the locomotive is fully lined (whenever I get around to that) I'll pose it with a rake of the Trix coaches and post the photo. They are actually quite impressive coaches, although you can't run them on anything other than Trix Twin track unless you replace the steamroller wheels. Fortunately the dimensions of the Trix and Dublo axles seem to be identical, so replacement of the wheels is fairly straightforward.

    The replacement 60 Class tender underframe is completed and awaiting fitting to the tender body. I modified the rear of the underframe to accept a Dublo type coupler (in this case a Peco one). I might be tempting fate with all wheels being flanged, but I have tested it and there is enough sideplay for it to negotiate Dublo curves and points. The tender wheels are, I think, Jackson products, if only for the reason that I happened to have some handy. The tender will be heavier than average, thanks to all the thick whitemetal castings, so that should help to keep it on the track. I intend to use two pieces of wood running crosswise in the tender, one to keep the end in place and another to screw the underframe to the body. I will also put an 8BA bolt at the front of the tender, through the floor, and this will also double as an attachment point for the drawbar.

    While I was painting the wheels of the tender, I also painted the wheels of the locomotive chassis, but that's all I'm doing with the locomotive chassis (or, for that matter, the locomotive body) until the tender is completed.

    A bit of adjustment is needed at the front end, but it's beginning to take shape.

    Well, to get everything looking more or less right, I had to lower the footplate under the cab by about 3mm or thereabouts. The locomotive appeared to be higher than the tender - it seems that GWR locomotives (I am using bits from a Tri-ang Hall) have slightly higher footplates than other railway's engines, hence the buffers that are closer to the foot of the buffer beam than the top.

    A bit of work and it now looks like this:

    I seem to recall that the buffer heights of Tri-ang locos were some 2mm higher than they should be anyway :scratchchin:

    Something like that, maybe a bit more. But the front buffers on the Hall are lower on the buffer beam than you would expect. I'm not a GWR person, so I don't know how accurate it is in that regard. I just want it to look right. I don't care if it's not 100% dimensionally accurate though.

    Yes the Hall buffers are lower on the beam. The beam was deeper as well.

    Well, it's almost done. I still have to rework the front buffer beam and fit handrails. The casting for the Westinghouse pump from the kit is very poor, so I won't use it and will fit something better once I get my hands on one. As you can see, I used the footplate from the Hall body (after sawing off the superstructure of the Tri-ang body) because I thought that might make things easier. In some ways it did but, next time, I might just use what's in the kit and modify it to fit whatever chassis I use. Here's where it's up to now:

    Hiya,
    Haven't been along for a while, so I had some catching up to do.
    Great progress on the class 60 loco project!

    At my end the Dublo railway has taken a bit of a backseat apart from the odd running session, as work at SNCF has been crazy since the summer and continues to be so, probably until the Olympics are done and dusted next Autumn.
    Added to that, the camera on my iphone conked out for some unknown reason and I haven't got round to replacing it (unlike Dublo these things are pretty hard to repair :whatever:.
    Anyway I finally got around to finishing 6234 in experimental blue with its Methfix transfers (I've never used them before, only the water applied Pressfix type), a bit of a faff to apply, and I came perilously close to a complete disaster on several occasions during the process, but at last the job is done, and I must admit I'm really pleased with the result!
    What a beast! I think the LMS were onto something with this livery, pity they got nationalised in 1948. The colour and the lettering style really suit the class. Smoke deflectors were a must, I’m looking for a second set for 6231 as the locos really look a bit weird without them, almost « undressed ».
    Does anyone know if the LMS had plans for new coaching stock liveries to go with these? 6234 is running with either Pullman’s or a rake of early BR crimson and cream coaches for the moment.

    I had to steal my sons phone while he wasn't looking to do these and upload them, so they're not the best. No photo of the smokebox door either with its paper printed numberplate.

    Maybe the blue is a bit dark, but it is less so in reality and is certainly miles better than my initial Gordon the Big engine blue ! Note the nearly finished glass of Cote du Rhône and the half empty bottle in the background, these may explain why that M on the tender looks a bit crooked :giggle:. Also she needs the 8P power classification to be applied under the number on the cabside, but overall the 1946 plain block straw lettering looks really good. My DIY nameplates also look OK (at least to my failing eyesight!)

    Hello All, re the LMS loco blue. bearing in mind that the senior BR Locomotive men in 1948 were primarily from the LMS, and that there was a series of locomotive livery trials in which some shades of blue were considered, then it is reasonable to assume that the final BR locomotive lined blue would have been the same as LMS blue if nationalisation had not taken place. ( Reasons for Nationalisation is a whole complex subject of itself ! ).
    BR locomotive blue was intended for top flight passenger express locomotives only, with the second division being lined locomotive green, the third division of mixed traffic locomotives lined black ( x LNWR ), and the last division of unlined black.
    The LMS had intended to only have two locomotive liveries, straw lined black, and plain black, so the LMS blue proposals was likely dictated by a need to publicise improved mainline services as maintenance arrears were addressed. It was also a combination which could be applied relatively quickly, and give a favourable public image of things returning to normal.
    Going back to LMS straw lined black, this made sense as it was a simple livery to apply, and it was cheap. The initial BR thought on locomotive liveries was green for passenger, and black for goods locomotives. I understand that it was E S Cox who suggested Mixed Traffic Lined Black, as it was cheaper , and less complex to apply than green which made sense in Post War austerity. ( So your BR lined blue B12/3 is fictitious, but good looking anyway ! )
    With the passage of time, BR Locomotive Blue was found to weather badly, and weather a lot quicker than BR Green, as well as being a more expensive colour to apply than green, hence the decision to replace blue with green.
    The use of lined black in lieu of green was also a significant cost saver. The 1950s BR Southern Region locomotives painted green were pretty much restricted to the big engines like the Lord Nelsons and Pacifics, with all else being either lined black or black. Towards the end of the 1950s lined green was extended to other classes ( anything with a nameplate usually, hence Schools got green ! ) and by the 1960s you even get BR Standard 2MT 2-6-0s from Swindon in lined green. ( If workshop times at a premium, unlined green and unlined black was resorted to. )
    BR coach liveries are also interesting in that mainline Red&Cream, with secondary coaches in Red gave way to the darker shades of Lined Maroon and Plain Maroon, again due to weathering, where it was found that darker shades retain a clean and cared for look compared to the lighter shades. This may also explain why the BR-SR did not return to the lighter Malachite Green that Bullied used. ( Yet, John Deere tractors use a high gloss lighter green to make them stand out, and look clean, from a distance, subtle marketing. )
    Finally, it also turns out that there was a difference in the green used by Eastleigh, and those workshops to the North. Despite a "standard" livery specification, different workshops used different sized numerals, and in some cases, different positioning, hence Inverurie used larger numerals than either Darlington or Doncaster for example.
    LMS 6234 looks good in blue, the Stanier Duchess/City are such a well proportioned design that any colour looks good on it, Regards to all.

    Added to which, R A Riddles was an ex LNWR man. I recall reading, in a biography of Riddles (which, regrettably, I no longer have) that in the first parade of the proposed liveries there were several Black 5s finished in different schemes. At the tail end of the line up was an unannounced example in what was to become BR lined black. One of the officials turned to Riddles and said "Riddles, you ba****rd".

    At the experimental stages of BR livery, some coaches were finished in a simplified version of the LNWR livery.....

    The post-war LMS blue grey colour was an experiment confined to one Duchess and one Jubilee as a proposed new livery. The decision, however, was to stick with black.

    BR blue varied a bit, with early examples being darker, and some A4s with a slightly purplish hue. Eventually it settled down to a standard shade, but apparently the Duchesses painted at St Rollox during this period were finished in a light sky blue, as used by the Caledonian (and defining Caledonian blue is something that would need a whole thread in itself).

    I love the way pride in the old companies lasted throughout the grouping period, and reared up again in the early days of BR. The domination of men from the LMS and their various constituants must have been pretty galling for everyone else, especially the GWR.
    Swindon maybe got its revenge in the end though, when lined passenger green was adopted for express locomotives. Better still, they didn’t even have to change the four digit brass numberplates fitted to their locomotives - I’ll wager there was some pretty heated debate about that in 1948!
    Their biggest snub, and last hurrah to the powers that be in Euston though, was the adoption of diesel hydraulics rather than diesel electrics under the modernization plan - complete with brass name and number plates. Obviously :giggle:
    There are as we all know, only 2 ways of doing things :
    the Great Western way, and the wrong way…
    I’ve always felt the GWR was only finally smothered when the last class 52 Westerns (they never got TOPS numbers either - those brass numberplates again!) were withdrawn. Not a bad record, 1833 to 1977!

    Off to pick up her train. So Dublo connecting rods are not steel, but plated brass?

    Going off on a tangent here, but the Highland Railway staff took very enthusiastically to the new LMS livery and painted virtually any locomotive that was likely to haul a passenger train in crimson lake, even small 0-4-4T and 0-6-0T engines. Even the 0-6-4T banking tanks that were stationed at Blair Atholl to help heavy trains up Slochd were fully lined out in crimson lake, presumably because they occasionally were used on Blair Atholl to Perth local trains. But the crimson lake suited the Highland engines particularly well, so much more so than unlined dull green.

    And St Rollox works (Caledonian) frequently used a different size of lettering from what they were supposed to after the Grouping.....

    Hello All, it was the BTC in 1950 who decided and directed that the WR would use diesel hydraulic on the basis that WR train running was fairly self contained and this would allow for practical comparison with diesel electrics elsewhere. At one point in the late 1930s, the GWR considered electrifying west of Taunton, and in early dieselization the WR did pursue dieselizing Cornwall and Devon first. Also at this time, the German Federal Railways / DB was the prime advocate of diesel hydraulic due to both light weight and a better power to weight ratio compared to the then available diesel electrics. North British Locomotive / NBL had a license for MAN diesel and Voith hydraulic transmissions, and Bristol Siddely licensed Maybach diesels and Mekhydro transmissions.The other aspect of diesel hydraulics that is rarely mentioned is maintenance by swapping out defective motors or transmissions at major depots, eg Plymouth Laira, whose diesel shop was equipped with heavy duty overhead crane for this specific purpose, whereas other Regions whose diesel suffered a major breakdown sent the miscreant back to the central workshops. In the 1950s and 1960s diesels were presumed to be more efficient but were still allocated, and rostered as a steam locomotive with a longer range. BR was not alone in this concept. The idea of dieselizing districts was pursued by both the ER and WR, and where a lot of traffic is contained within a district, there is some sense to this. But, as more diesels enter traffic, then increasingly they need to work into steam strongholds, and some of those locations have greater traffic interchanges. This in turn leads to longer point to point rostering, which leads to concentrating particular diesel classes to particular long distance services, which also has a knock on effect with related, and adjacent traffic. (The North East - South West Route became the province of classes Sulzer 45 & 46 for this reason.) With the passage of time, improved reliability and higher utilisation, combined with falling traffic, this leads to a surplus of diesels, in BR's case, to the extent that reliable classes like the Westerns and Hymeks get withdrawn as they increasingly become a minority fleet in a sea of standardised diesel electrics. With the passage of time, the power to weight advantage of the diesel hydraulics was slowly whittled back by newer, and better reliable diesel electrics, and even DB has abandoned mainline diesel hydraulic locomotives, though diesel hydraulic DMUs are now all the rage ! These days repair by swap out replacement at out stations is pretty much the norm, hence the gradual run down, and closure of both diesel depots (Bristol Bath Rd) and workshops (Swindon) is a by product of this. In the 1960s and 1970s , diesels were usually stabled at MPDs, or railway station sidings not accessible to the public. As newer diesels got larger fuel tanks, stabling locomotives out in the open became accepted practice, in which case MPDs were also closed, and usually demolished.

    The 60 class hasn't had its coat of "shop grey" yet, but it's now in service without any major issues, just some very occasional phantom uncoupling and a slight hesitancy over one point. A bit of fine tuning needed, but it's looking and running well. It easily copes with four Dublo tinplate coaches (the maximum train length you can reasonably run on an 8'x4' layout) and could probably take two or three more if I felt so inclined. Here it is:
