    Perhaps we should ask Dr Strabismus (whom God preserve)...

    I can’t wait to see this. Every time I go down the Bluebell I am looking out for a glimpse of the work being done.

    It is going to look amazing on the Pullman trains one day.

    Well done everyone involved.

    -I'm guessing that the engine will once the boiler is ready for hydraulic tests and steam test will be moving into the workshops for final assembly so as to not waste too much boiler life once the ticket becomes live , what's the situation with the tender tank ? as I'm assuming this will now gain more importance if the loco chassis is finished, boiler work leading up to the hydraulic tests is done, your going to need the tender to be ready to move when the engine is ready to have the boiler refitted .

    Thanks very much for posing that; updates arrive sufficiently infrequently that I don't check its site, but this was a great update; really getting there!

    Another one I don't check is the Bluebell Standard (84030), which I see also has a recent update; I didn't see a thread here for that one, or I'd have posted a note there..

    I'd have though they'd want the tender completed and ready to go before they start the clock ticking on the boiler?

    Will be a beautiful machine when finished, really add something different to the bluebells fleet, not to big or to small either. Nice seeing it looking more complete as time goes on

    The tender frame was being used to store the tubes before fitting, and as is clear from the report, the access to tube the boiler means that construction of the tender body can't start until the boiler was tubed (at least not with everything in its current position). Last I heard, the tender tank will be assembled in house from pre-prepared sheet.

    With regard the boiler ticket and ticking clocks: as I understand, the boiler can have a hydraulic test without any clock starting.

    There are spatial constraints to the next steps. As I understand, the tender underframe will need to come out of Atlantic House, followed by the boiler (which is behind it in the building). They will come out essentially at right angles to the main track layout, so will probably have to be turned; therefore that move will need to co-ordinate with an external crane hire: normal practice is to line up a number of jobs that need doing to maximise use of the crane over the course of a day.

    The boiler can then have its initial tests as described.

    There will then need to be a second external crane hire, in which the chassis comes out of Atlantic House and the boiler and chassis are united. The whole lot will then probably go back into Atlantic House to finish assembly. Atlantic House has no overhead crane, so the union of boiler and chassis will have to be done outside.

    Thanks for those details.
    So, when does the clock start ticking - the first time steam is raised in the boiler? (Which, from the images I recall, is often/usually/always? done with the boiler out of the frames?) Is the insurance rep always there for the first steaming, or can they show up at a later one?

    Seems like a very prolonged way of doing things, I take it the bluebell don't have a working 45 ton steam crane then, to do the reassembly of chassis and boiler then a second possible lift to swing the completed engine 90 degrees onto the tracks unless your going to use traversing jacks ? with the boiler tubed then I'm imaging that you can start on the tender as the tubes are then not in the way so the tender could then go into the paint shop as its a wide firebox, can it be tested on the loco, some engines with wide fireboxes can be hydraulically tested and then steam tested in situ or with the boiler blocked up to clear the foundation ring ?

    Or in other words, given the choice you wouldn't start from there ̶ nor, probably, would the Bluebell if they had the choice. But they are where they are, and they do have a coherent and manageable plan to get from there to where they want to end up, with a lovely loco which many of us are keen to ride behind.

    Martin - there is no operational 45 ton crane. There are overhead cranes in the main workshop that could conceivably be used to unite boiler and chassis (they were used for 847, so I can't imagine there is any weight issue with 424), but you still have the issue that both boiler and chassis have to be turned by 90 degrees first. So at least one external crane hire would be needed regardless. In practice, there are other jobs that will also require an external crane (unloading 34059's boiler when it returns; rewheeling 84030 etc.), so in practical terms, the job to manage is simply about lining up sufficient lifts to do on one day.

    After the boiler and frames are united (and I appreciate we are getting ahead of ourselves here) there is still significant work to do, such as making and fitting the boiler cladding and any other final assembly tasks, painting etc. The preference I think will be to do those inside Atlantic House. They could be done in the main workshop, but at which point you take one of the two roads there out of commission, while leaving the valuable space of Atlantic House empty. Covered space for overhauls and repairs is at a premium, so in my eyes there is an advantage in keeping Beachy Head in Atlantic House for as long as possible rather than using space in the main works. There's no reason why it can't be painted there, as evidenced by the painting work already achieved on the chassis, cab etc.

    Can the crinolines and cladding be made up and set aside before the boiler is steam tested and put in the frames? Even if only most of it can be done first it'll save time on the ticket.

    I believe that in practical terms, the actual counting insurance test (which starts the ticket running) can be done with the boiler mounted, since with a wide firebox, the whole boiler can be inspected in steam down to foundation ring level while the boiler is fitted to the locomotive. So I imagine that the actual process will run something like hydraulic test (out of frames) - reunite boiler with frames - make and fit all the cladding, and then remove it again - formal boiler steam test - refit cladding - final painting and assembly. As with any loco, the objective is to do the formal steam test as late as possible, which is slightly easier with a wide firebox loco. Clearly the objective will be to have every component to hand before the steam test so that the last steps can take place as quickly as possible.

    Thanks james, that's very much how I would have envisaged it you could always once the boiler is in the frames and the insurance test done, and the engine is ready use a low loader assuming there is room to fit a low loader trailer outside Alantic house because if there was and you just happened to have an engine being delivered, or going away ,a simple spin round the car park and off load the engine onto the rail/ road siding may be cheaper if you can not get enough cranage jobs to make hiring a crane affordable.

    Pretty certain that there would be insufficient space to get a lorry parallel to the axis of Atlantic House (at right angles to the axis of the yard) to do that.

    See here: https://goo.gl/maps/FenW3XwXqt82

    Atlantic House is the building part surrounded by trees above the words "Pellingford Brook". From right to left, the tracks in the yard are labelled Tramway and then 5-road down to 1-road; and 3-road and 2-road have pits. So I can't see there being anywhere near enough space to load a loco directly onto a lorry - hence the need for a crane.

    Tom (by the way ...)

    May I enquire as to the plan for extracting 32424 from AH when the time comes, if it can't be done by lorry?

    Both the loco chassis and tender chassis are on rails in Atlantic House. So when necessary, additional temporary rails can be laid across the yard for sufficient distance to allow either loco or tender to be rolled out, and then using a crane they can be turned 90 degrees and placed onto one of the roads in the yard.

    What's going to happen to Atlantic House when Beachy head moves out for good?

    I would presume for the construction of their next Loco.
