  1. Looking good Pete!

     

    Every time I see your layout I get reminded just how high those tractors had to climb to get back onto the mainline!

     

    I also like how you have modelled the settling tanks, were those rectangular ones still in use during the 1980s or had the circular pools taken over? I'm thinking of modelling the circular type settling tanks on my layout, so if your pools are to be filled with clay I'll be interested to see how you do it.

     

    Kindest Regards,

  2. Sorry for the slow replies chaps,

     

    Guy, typically the rakes of PRAs were not too long and were normally part of speedlink workings, I think the most I have seen together was six. Perhaps this method would be well suited to the TDAs I have done to create the barrels?

     

    Scottish Modeller, you can find the PRA model here: http://www.shapeways.com/shops/rail3d

  3. Hi guys, thanks for the positive comments.

     

    Pete, on the locos I have the same configuration as the wagons, buffer beam magnet one end, elastic and magnet t'other, but I have a piece of steel wire vertically down from the buffer beam for the magnet to stick to, this keeps it bent round when not in use and looking like a brake pipe so it doesn't stick out like a sore rapido!

     

    Jon and Mike, the elastic is a little chunky for a scale brakepipe, but I think you can get smaller magnets though they cost more and I haven't found a seller on eBay. Certainly worth experimenting with, I'd be well impressed at seeing working brake and vac pipes in N that's for sure!

     

    Kindest Regards,

  4. Will, I think having the magnets side on would mean they are more likely to slide apart, there is little friction to be overcome when sliding the magnets over each other, which is good for uncoupling when mounted end on, but would reduce the "draw bar" strength and make uncoupling more difficult if mounted side on. The weight of the vehicles is enough to keep them in place, because you're using the nearest axle as the pivot point when pushing down the weight of the wagon has the mechanical advantage over you and because metal on metal presents little friction the magnets slide down and out of each other's fields easily.

     

    rcmacchipilot, the length possible will depend on several factors; The length/weight of the train, the ammount of fiction in the wheelsets and the tightness of the curves. I reckon 30 wagons if the curves are not too tight and the wheel sets are fairly free rolling, interestingly when you start a train you have to do it like it would be done in the real world, you have to take the slack out of the couplings before you put the real power down, otherwise you risk the front magnet disconnecting! If you want to run longer trains you can just add more magnets, have two, or even three end on in each buffer beam and you'll increase the coupling strength.

     

    Kindest Regards,

  5. Thanks guys,

     

    I'll have to look into lowering it, there is a much bigger gap (relatively speaking) than on the 4mm tractor, is there a "how to" around here somewhere?

     

    For the head light I plan to drill a hole in the nose and then mount a spherical bead cut in two on peice of wire bent through 90 degrees. Paint the back black and the front silver with a blob gloss varnish on to give that lens look.

     

    Kindest Regards,

  6. They look very nice. I might have to try the scale scene hoods - yours look better than my attempts at masking tape!May I ask what you did for the buffers? I am loosing my temper trying to fit the Parkside Dundas buffers recommended, as they are slightly larger than the holes!

     

    I used the existing holes as "pilot holes" and took a drill bit in a pin vice and opened out the holes to the same size as Parkside buffer shanks, I also wrapped a piece of masking tape around the drill bit so I knew how deep to go.

     

    I hope this helps;

     

    Cheers,
