    would there be any scope for modernising preserved locos do you think? Bigger tenders/tanks/bunkers perhaps? Higher boiler pressure? Bigger cylinders? Roller bearings?

    There is always scope, but you have to aks is it worth it and is it what the owner should be doing, the answer to these will depend on many factors. If the owner is a museum that is set up to preserve the loco I would say generally no, if the aim is to just having it running then may be. Ideally there should be a look at other locos of the same class, we don't want to end up with none of that class looking as they did.

    Some of these mods have already been done, the bigger tender idea is evident on "Repton", many tender tanks have had their capacity maxed out for operation on NR and I guess a certain A3 running with an A4 boiler counts as a big mod! Coal is rarely the issue, water is much more important!

    How about building a bogie tender with more water capacity. (just idle musings, it doesnt really matter how practical it is :)

    You mean like 825, 777 and 850 are all currently running with? I am sure there will have been other examples over the years in the UK and it was pretty standard for at least a part bogie 8 wheel tender in Europe.

    the mod to Reptons tender is not a preservation idea . IIRC some ran in BR days .

    many engines already have mods to them , be it rocking grates , Ashpan washers , self cleaning smokebox , TPWS , AWS , Tender alterations internal (more water capacity)or external (6233 and 61994 have obvious rear tender extensions )

    34092 and 78022 have been modified in preservation with Giesl ejectors . Some narrow gauge engines i'm sure have quite dramatically different exhaust arrangements (Lempor springs to mind)

    In most cases the changes are relatively invisible so the purist is happy and the operating department equally so

    The big issue for serious changes is costs as preserved line running is unlikely to generate the savings to offset the cost so unless you are rich (or have rich backers ) and do it for the fun of playing it's probably a non starter

    I guess the other thing you can count as modifying / Frankenstein is using parts of engines to make another loco , for example 7927 + 48518 = County or 4942 = 2999 or the cobbling together to make a 47xx (you may note i'm not keen on this ... you'd be right !)

    I think the mod to Repton's tender was done whilst it was in America/Canada (can't remember which).

    Has 5043 Earl of Mount Edgcumbe had a self cleaning smokebox fitted or was this fitted in BR days?

    Repton's tender was defaced in America. Why the new tank was built in the same manner is beyond me. It looks utterly hideous.

    referring to the Irwell Press book of the Schools both 30905 & 30932 had a high sided tender . One was modified and ran with both . The design is in essence the same as 30926 has now

    I am not totally sure that 30926's tender was extended in the USA. The extension to the present tank (built after the loco's return to the UK) was made at a time that mainline running was being considered to increase coal capacity - arguyably not the same issue on the NYMR but still useful, as is the extra protection from the elements when running tender first! (Ask any crew who had the the S15 in reseverse in a down-pour or blizzard!

    I am sorry if some observers don't like the appearnce!

    Afraid i have to disagree there, it works on 60163 as a product of the 21st century but on anything else it would be hideous.

    At the SVR gala in the dark everything looked lovely and authentic with traditional headlamps, then Tornado came round the corner with the floodlight gantry from St Andrews...

    Battery lamps currently in use on the Mainline are sufficiant so why go to the cost of thousands of pounds of modifications when it's not a requirement ?.

    inspection lights á lá SR pacific would be a good idea I imagine

    My view is that modifications that improve the engine but don't alter its external appearance are OK and might well be beneficial. I'm thinking of features like self-cleaning smokeboxes, rocking grates, and roller axle boxes.

    But not original thinking as it's only following what BR did to quite a number of A3's

    Thanks Martin - I have a feeling the current version is slightly different and sticks to the design that did run with a couple of locos in BR days as you previously noted. The picture in the US looks as though it may be even higher sided.

    I tend to agree with David - I am all for modifications to make operation of the loco easier. I know a major complaint of crews who end up disposing at Pickering at gone 19:00 or 19:30 (depending on the timetable) is having a loco that doesn't have a rocking or drop grate or hopper ash pan. I have also heard the alternative view that the lack of such kit is part of the heritage of steam and if you start modifying, where do you stop (big ringfield motor in the tender?).

    Some of the modficiations are so well concealed that they can end up being missed. A few years back, a Moors driver who also drivers for a TOC as a living careful bailed out a loco with the fire irons. The Duty Fitter, who had had his fill of being told how things were done on by professional railwaymen during the course of the day, stood and watched. When the job was done, he asked "is that how you professional railwaymen do it, then? Us amatuers do this" and duly unlocked the rocking grate, put in the handle and dropped the last bit of fire with a couple of sharp moves of the rocking grate!
