  1. Can't talk about other companies, but CR fish wagons, some of which were basically 8T dropsides on passenger rated underframes, were painted in NPCS livery of dark purple brown with yellow lettering.

    Now arrived at Aching Constable carriage works....

    Of course, having viewed the photograph I was horrified to see the ghostly reflected image of a malignant entity from Beyond towering menancingly over my carriage prints. It was chilling to think it was in there, with me, invisible to the naked eye!

     

    Then I realised it was bird sh1t on the window pane.

     

    Panic over.

     

    These will keep you out of mischief for a wee while (or perhaps not!).  That is after you've washed the windows of course!😉

    The characteristic train on the WHR / Extension was the fish train. 

    A fellow 2MM SA member in our Area Group is building a model of Glenfinnan in 2FS and is in the process of assembling a lengthy train of Foxhunter LNER fish van kits.

    However, in the early days, the Scottish railways seemed to have used passenger rated (often dual fitted) open wagons for fish boxes packed in ice. In 4mm scale, NBR 4mm Developments make a kit (https://www.nbr4mm.co.uk/wagonkits/9100.php) in the larger scale. This includes a useful history of the wagons and this drawing.

    Yes, the CR had similar fish trucks which were Dia. 15 dropside wagons whose underframes had been ungraded to passenger train standards.

  4. Surely the important criteria for what wagon was required was the nature of the load?  The load weight marking on a wagon was governed by the running gear.  As @Mol_PMB has said above, you would only need a shallow wagon for a high density load, such as sand or loose root vegetables, while a low density load, such as hay, would need a wagon with higher sides, so the request might be more nuanced than 'we need an 8T wagon'.

  5. If the loco runs well on DC and like a donkey with the chip then the issue lies with the chip.  Try a different chip or try tuning the chip.  Can't help with LaisDCC decoders, but these articles might help with CT and Zimos.

    It's well worth investing in a SPROG and using  JMRI to do the programming on a test track.

  6. Although working in 2FS rather than 4mm, I can attest to the quality of Zimo decoders having 4 locos fitted with them.  I also have several fitted with CTelectronik ones, which are also good, but unobtainable at the moment.  These two are the only makes (at present) which have small enough decoders for my uses.  I am lead to understand that the shortage of both these makes is due to the manufacturer being fully occupied with providing components for the German Military, and we all know the reason for that!

    I don’t know what the prototypical capacity would be, although I’ve rarely seen pictures of J94s with more than about a dozen 4 wheelers in tow except in preservation where their Austerity cousins seem to be regularly tasked with 5 or 6 BR Mk 1 s.

    I see no point in getting obsessed over trying to emulate the haulage capacity of the prototype.  Unless you have a big layout like Fencehouses or CF on which you can run prototype trains, what's the point?  For me all I want is for a loco to have sufficient adhesion to haul the train I envisage for it.   Weight is always going to be the limiting factor, never motor size.  I recently replaced a Branchlines Minimotor (iron cored) in a little Drummond 0-4-4T with a Tramfabreik 0615 (coreless).  It will still comfortably handle a train of 5 4-wheelers, which all I ask of it.  (And the wheels still turn if you put an obstruction in front of it!)

    The J94 has one of the Association 7x16's in it with a two stage drive and seems to be very good at polishing rails if progress is impeded, something I'd put down to lack of mass to stall the motor! 

    What do you mean by 'if progress is impeded'?  Impeded by what?  A finger - yes the wheels will spin, but what is it's haulage capacity in terms of wagons?  Why would you want to stall the motor?  That's just going to draw current.  I have a white metal bodied 0-6-0T which will haul 35+ wagons, three times what my layout is designed to handle and yes, put a finger in front of it and the wheels slip.  Remember too, that if you have a whacking big heavy motor in the tender which is driving the loco, then that motor becomes 'train weight', so the loco needs more weight to have sufficient adhesion.  Weight in the loco for adhesion is what is important, not the size of the motor.  No point in having a motor which can provide more power than the loco is able to deliver at the wheel-rail interface.
