    Apologies for the late reply Adrian, I didn't realise the GE modiified it's loco's in the is way but as you say it seems to make sense. I'm only used to seeing the little L&Y pugs or sentinels in the North east for working those tight dock lines. I look forward to seeing one turned out for your collection,

    Quite fancy one of those myself except I've got 6 engines ( no hang on, finished one..) make that 5 engines, on the WB already!

    Space for one more then JB!

    Speaking of space for one more; milled parts for a GER C32 2-4-2T arrived in the post this morning c/o CME Dowling of the Southend Loco Works. Brutish looking tanks, with their 5' 8" driving wheels and outside frames for the leading and trailing wheels, they were very much at home on the heavy and fast outer-suburban services into Essex and Hertfordshire.

    So what is the purpose of the flap doors at the bottom of the bunker?

    Looking at the detail of the photo, I now know what to do with the spare thumb tack "buffers" from ABS kits - just like the crank pin nuts :rolleyes: .

    Rather purposeful looking tank loco that but will it effectively be an 0-8-0 from a rigid wheelbase perspective or did the leading and trailing wheels have allowance for lateral movement of some kind?

    The flap door in the bunker gave access to the springs over the carrying wheels.

    Yes, essentially an 0-8-0, but when Colin built his LNER version he found it was able to go through a B7 turnout...with ten thou clearance between wheels and frames.

    The prototypes were double-framed fore and aft, the inner journals having no collars and the axle being free to move laterally. The outer journals had collars and allowed one inch of uncontrolled sideplay. As all the side forces were carried by the outer frames they soon began to crack, and were quickly given control springs of india rubber within deeper axleboxes from 1894 onwards, the inner frames were altered to give an extra half-inch of sideplay. No official explanation of how this was achieved has been found, but it is assumed the frames were recessed or dished somehow, though how this was managed in the vicinity of the cylinders is a bit of a mystery. Interestingly, staff who worked at Stratford from the 30s onwards have no recollection of these springs (so Colin's uncontrolled axles are almost certainly prototypical), and the LNER may instead have fitted an arrangement of inclined planes on the spring bearing plates, but the Engine Repair Registers neither records this, nor the control springs being removed.

    For my model I'm probably going to fit some form of side-control springing.

    If this is for you, how does the engine fit into the scenario of Basilica Fields?

    Outer suburban services to Hertford and Bishop's Stortford.

    So the F3 running through The Rookery shall exhibit cracked frames as per the prototype.... :rolleyes: .

    Mind you, cracks in the frames is not the expected way in which we gain flexibility for getting S7 stock around tight curves :D .

    regards, Graham
  10. Since this loco was the tank engine version of a T26 2-4-0 (LNER E4), why not see what was done on that?
    (Preserved prototype is at Bressingham, or was last year.)

    So you have cracked frames already? I did know that you were one for fidelity to prototype....

    Not quite; SO R33 - the 108x series and the first to have condensing apparatus - were built in 1894, and as the frames remained intact for a while I'll leave mine unsullied.

    Because despite their familial similarities (and you can lump the 7'0" T19s and the D27 2-2-2 singles into the mix), they were different in that area - only the tanks had side control springing, revised axleboxes and frames. The T26 at Bressingham mirrors what was present on the first batches of the C32s for only the first couple of years of their lives.

    Good man! :)

    Oh I would... (I will eventually) but I already have a (mostly built) F5 awaiting some radial trucks !

    I know, I know, I'll get round to it eventually...

  16. Huh. Last time I make a suggestion to help you.

    Hi Adrian have you got any photos of the inside of the poundsberry wagon that you built I'm interested in the strap and bolt detail

    It's been a very busy few months in modelling and non-modelling terms, but now as things are calming down a little I've got time to download and sort through some of the photos stored on my camera from the various building and painting commissions.

    Jim McGeown of Connoisseur Models asked if I’d decorate a Queen Mary brake van he'd built in the EWS livery as a counterpoint to the predominantly 1940s/50s stock he already has on display on his exhibition stand.


    Following the brief, in this livery it’s not an exact copy of the prototype as ADS56299 had the verandah sandboxes removed and the lettering was of a stencilled pattern, but it gives a good impression of what comes in the kit.


    It was lots of fun to do such a disgustingly modern (and worryingly attractive) livery for a change, and Jim was so pleased with the result he handed me another to do, but this time in Southern brown and vermilion.

    More to come...
