RMweb Premium Michael Edge Posted December 31, 2019 Author RMweb Premium Share Posted December 31, 2019 The fiddle yard is filling up now but there's still room for another coal train (only 145 coal wagons on here now). Looking towards West Silkstone Junction, two bankers waiting to return from the original crossover with the new one in the foreground. It does occur to me that this new crossover will make a big difference when operating Herculaneum Dock as well. It means that all goods trains will be able to use the sidings at the front, leaving just the coal trains in the back loops, most of the loops can be just for passenger trains. Here the occasional LCGB special, pulled by a D10 is parked in one of the kickback sidings and there are a few strange stock items (I'm running out!) such as a GW brake van and the 4F on coal empties. From the other end, far left is a 50 wagon train of empties (these will only fit in the first two loops), next a parcels train which I believe put in occasional appearances - even hauled by an EM2 in later years. Last up train here is the petrol tanker train which has to have an assisting engine attached to creep down the hill - at least until the EM1s appeared with regenerative braking. On the down side a train of about 25 large capacity coal wagons with an O4, these should be loaded but most of these wagons haven't been used much fro a long time and need some maintenance. Next road is a "might have been" with an NER Bo+Bo - these were kept until 1951 for use here but never worked again after the Shildon line was de-electrified in 1935. Next on a mixed train is another near miss - the solitary EB1 was intended to work here but went to Ilford in 1949 instead. Finally another O4 with a half train (30 loaded wagons) which is the longest I can attach a banker to at the junction. The last road and two of the kickback sidings might be left clear to run the colliery trains, I'm still waiting for the baseboards to go across the middle so these can't be run properly yet. 18 Link to post Share on other sites More sharing options...

RMweb Premium Michael Edge Posted January 7, 2020 Author RMweb Premium Share Posted January 7, 2020 Since all the wiring for the points was in place I wired up to the switches in the control panel and removed the faintly ridiculous wander lead arrangement. Panel in place All the boards have been marked for positions of magnets, gaps, feeds and links across joints. Testing (playing?) now suspended for a while since the rest of the wiring will be done one board at a time in the warmth and comfort of the workshop - might interfere with work a bit though, some of these boards are quite big. 12 Link to post Share on other sites More sharing options...
RMweb Premium Popular Post Michael Edge Posted January 14, 2020 Author RMweb Premium Popular Post Share Posted January 14, 2020 One board at a time brought into the workshop for wiring at the weekend. These boards are a bit big and Judith's kit stuff occupies some of the big bench. Some work on the top first, the new Peco rail joiners are amazingly good - not only are they suitably short and actually look like fishplates but they grip the rail very well. I won't rely on them for electrical conductivity though, all joints have been wired round now (this wire will be buried in the ballast). The V marked on the board shows where a gap has been cut in one rail for a section break, I usually try to arrange these in pcb sleepering but sometimes this is unavoidable. However it is necessary to prevent the rails from sliding in the chairs and closing the gap, here I'm trying out a small fillet of epoxy (Super Steel) in the gap. The board stood up on its side to do the wiring, some labelling done as well. The deep baseboard edge on one side makes this quite stable, usually I have to use a G cramp to secure boards like this. While the board was out it seemed a good idea to do most of the work for the ashpit, lining the sides of the cutout with brick plastikard. Sleeper ends will be trimmed a bit later. View of the ashpit from underneath. The next board with the wiring more or less complete, two plugs at the top connect to the control panel which is attached to this board. Back out in the shed next job will be to plug it in and see if it all works... 19 1 Link to post Share on other sites More sharing options...

Thanks, Paul. No, despite the name it's completely insulating - I also use a smear of it as insulation on parts of locos where bogie wheels might touch something. The other main use for it is to add rivets (either forgotten or awkwardly placed ones) since it shrinks to a hemispherical shape as it cures - as long as you dab the same amount on each time you get a row of consistent rivet heads. 1 1 2 Link to post Share on other sites More sharing options...

RMweb Premium Michael Edge Posted January 15, 2020 Author RMweb Premium Share Posted January 15, 2020 Plastic Padding Super Steel, there is another "super steel" from Loctite which is something completely different. Plastic Padding filler has now become "Teroson" but it's the same stuff, Super Steel (at least on Halfords shelves) is still branded as Plastic Padding. 1 5 Link to post Share on other sites More sharing options...
RMweb Premium Michael Edge Posted February 18, 2020 Author RMweb Premium Share Posted February 18, 2020 Some more loco testing on WJ. A green EM1 attached to the front of the class A tank train for braking down the hill - they didn't really want to pin the brakes down on this one. The loco was built from one of the DC kits mouldings quite a few years ago, it has the prototype of the bogies I will use for the etched version. One of the available Garratts has put in an appearance , seen here on the ashpit. Slight snag with this loco, the throwover on the leading coupler is so great (it's pivoted though) that it won't hook on to the train coming off the pit - so it will have to stay off this duty. It does have to go up to the pit (along with all the other steam bankers) for coaling though - it stayed out here all week, only returning to Mexborough for boiler washout on Sundays. The magnet in the foreground is where the train of fulls from the pit is left for the banker to pick up and pull out on to the up main - it's on a very sharp curve. 17 Link to post Share on other sites More sharing options...

RMweb Premium Michael Edge Posted February 19, 2020 Author RMweb Premium Share Posted February 19, 2020 Your Ratio bolster is on the front end of a long train of empty steels so it's doing even better than you imagined, your loco as well in this photo Baz. Yes the bankers will be coupled on to the trains, they shouldn't be but the gradient stops at Silkstone No.2 tunnel on the layout. This should be the steepest part so it would look wrong if the bankers started to drop off here. The problem with the Garratt is picking up the train off the pit, the front coupling misses the one on the brake van - even though it is pivoted is is lightly sprung central. No problems with the trains on the main line but the curve into the colliery branch is about 30" radius and using a banker for this is essential. It was also as far as I know the way it was always done until the crash involving two EM1s which the signalman had forgotten about - at this time the two bankers would pull the 30 wagon MGR train out on to the up main (the wires went as far as the signal on my plan), diesel loco back on the front and the whole lot up the hill, which confusingly is the down line. According to Alan Whitehouse if running round was required the loco used the next crossover at Kendall Green (fiddle yard for us) but mostly the trains went towards Wath rather than Barnsley Junction. 2 Link to post Share on other sites More sharing options...

OK so here's an idea, if that's the way it always works. You could bias the Garratt coupling to one side so that it would mate with the one on the brake van.

You could bias the Garratt coupling to one side so that it would mate with the one on the brake van. Another thought - if you need the coupling to be sprung to the centre for other situations, put an off-centre magnet up the pit road so that it pulls the coupling across when you need it to.

Baz Yes but it didn't work very well and the idea was abandoned in favour of pivoted couplings. Not sure what an extra magnet would do here, there's only a brass hook on the loco. It shouldn't really be a problem, for the steam era the Garratt is unlikely to be on its own at the junction, there were usually about 5 or 6 bankers working here at any one time. For the later full electric period the EM1 and EB1 have no problem here - at this time no locos were kept at WJ, a loco would be sent out from Wath or Barnsley Junction to meet the colliery train. There are going to be some other restrictions, for example the loco on the up class A tanks will have to have a full coupling (with loop) on the front to make sure that a banking loco can be attached to it for the descent. 1 2 Link to post Share on other sites More sharing options...

RMweb Premium Michael Edge Posted February 29, 2020 Author RMweb Premium Share Posted February 29, 2020 Meanwhile the colliery branch is taking shape. The branch starts off on an embankment, followed by a cutting. There is a stream in the dip in the middle and an occupation bridge across the cutting to make the scenic break before the fiddle yard. View from the other side, with the change in land levels this makes a rather deep baseboard. This will be the view from the junction, the curve looks sharp but it's actually 38" radius - well above my minimum. The part with track on is supported by plywood longitudinals which should prevent any sagging, although seeing as this is a colliery branch subsidence wouldn't be unrealistic. This is the gap to the fiddle yard which will be filled with a simple lifting flap - access through here without ducking under anything is going to be essential. This is a close up of the Templot drawing seen on the layout in the previous photo. It's a bit complicated since the track along this edge of the fiddle yard is my EM test track with the inner rails at 16.2mm and 18.2mm gauges. I'm still not sure how to build this, I've just superimposed a length of EM plain track on the point template. The switch can be made as a partial stub point with one blade on the common rail and both the others moving with the tiebar - the EM gauge only has to run straight. The dual gauge frog might be a bit more difficult but I'll see how I get on while I'm building it. It's only fiddle yard track, it doesn't have to look prototypical but it does have to work reliably. 7 Link to post Share on other sites More sharing options...
RMweb Gold 5BarVT Posted February 29, 2020 RMweb Gold Share Posted February 29, 2020 I’m not a track builder, so may be barking etc. Does it matter which side of the EM test track is the common rail? If this is the only point in the dual gauge it would be much easier if the ‘lower’ rail were common. If the OO has to start with a common ‘upper’ rail, might it be easier to do a common rail swap to get the easier construction at the turnout. (Melbourne Southern Cross had a set of switches to swap the side of the common rail.) Paul. 1 Link to post Share on other sites More sharing options...
