Popular Post LNER4479 Posted November 3, 2023 Author Popular Post Share Posted November 3, 2023 Now then, forgive me for getting just a tad excited ... Apologies for poor lighting. Just a quick snap from 1am this morning (!) Yes - we have one quarter of a roundhouse! Set desired road ... Loco moves on to 'table Turns to line up with exit track. And moves off to pick up southbound working (or at least it will once the track beyond is connected up!) In truth, only the tracks on the turntable are energised at the moment. I'm going to wire up these six roads first as a bit of a test to try and identify any pitfalls [sic]. More soon 35 11 Link to post Share on other sites More sharing options...
Popular Post LNER4479 Posted November 4, 2023 Author Popular Post Share Posted November 4, 2023 (edited) Meanwhile More work required at Carlisle No.13 to complete the installation down that end. Here's the little problem. Installation of the headshunt gets in the way of the rodding to the pointwork. And the rodding is required because some fool planned all this to be located on a bridge (meaning that point motors mounted directly underneath is not an option 🙄) One can be operated using one of those handy 'side on' Peco motors; the other works as part of a crossover so is being rodded from the other point. A rather satisfying, albeit time-consuming and fiddly, way of doing it, using the tried and trusted GEM cranks. As this is all somewhat remote from the operating position then I've set up this interim lever frame installation. It can't go there ultimately as that's where the M&C trackbed goes(!) but most of the wiring at the other end is permanent. Long loops left at this end for now pending final installation. And there we have it (for now). Carlisle No.13 pretty much as it will be. The motors for the two trap points can wait for now - their absence does not hinder immediate operations. You can see from this pic how the two points concerned are unwittingly plumb dead centre on the bridge over the M&C tracks. A close up of the rodding arrangement. And another, to prove it works! Which - dare I say it myself - it does, rather well. More soon - most of this new trackwork is now live. I'll do a demo post once it's completed.

RMweb Gold lezz01 Posted November 4, 2023 RMweb Gold Share Posted November 4, 2023 The way I see it is you have two options. Either make the head shunt shorter by the length of the buffer stop or make the head shunt an inch longer so that the rodding runs either side of it.

LNER4479 Posted November 5, 2023 Author Share Posted November 5, 2023 All done now chaps - ain't gonna change. The length of the headshunt is critical. The first associated point leads into the carriage shed - the headshunt as laid will take a smallish tender loco (a 4F was used to size up) plus 4 local coaches (57/60ft) which is practical for ECS workings to / from Citadel. (my Upperby carriage shed will be two-road, approx 6 coaches in each round. Used for stabling local sets only). 7 1 Link to post Share on other sites More sharing options...
Popular Post LNER4479 Posted November 5, 2023 Author Popular Post Share Posted November 5, 2023 (edited) And so the current bout of wire strangling on the new Upperby running lines is complete. By way of demonstration... The Upperby operator gets control of a train from a handover length of track just before Carlisle No.13. Here, the demonstration train turns off the mainline and accesses the down goods reception line (despite it being a rake of coaches in this instance!). Independent goods lines immediately behind the train. Train comes to a stand at Upperby Junction (Carlisle No.12). Direct access in to the main Upperby goods yard was not possible, so far as I can make out, so ... Train then moves forward straight across the junctions to access the lines that eventually led to Crown Street Goods Depot. This is a somewhat simplified arrangement compared to the prototype (believe it or not) but is the only way I can figure out how to get the train into the yard. It's a single track arrangement on the model but it'll open out into a double track formation. A second loco then hauls the vehicles across into the main yard area, accessed from the so called 'third line' which on my scheme serves as the headshunt. With the train set back into the yard, the released loco can reverse out, in this case using an alternative route into the yard area. And makes its way on to the shed ... except at this point it grinds to a halt. For now. Depot wiring to follow shortly.

RMweb Gold Tony Teague Posted November 6, 2023 RMweb Gold Share Posted November 6, 2023 On 28/10/2023 at 23:54, Tony Teague said: I am very comfortable with electrics, but a bit allergic to electonics where I don't understand what is going on, so whilst my layout and control of it are complex, almost all of it relies on fairly traditional switching. There isn't really a special design, it's just an extension of normal / basic switching in which one lever or switch on the panel operates multiple devices by firing one or more relays. I use Gaugemaster GM500 relays which are latching, and can be triggered using the same voltage as used to fire a solenoid point motor - so they are literally wired in parallel with those, and sometimes they are in multiple. I use them to change polarity, to light indicator lamps on the control panel, to switch off the feed to conflicting tracks, and even to reverse the polarity of servo feeds so as to raise or lower semaphore signals that reflect the direction of the point setting. They use very little current and so I have locations where my CDU might be powering 2 or 3 solenoids plus 2 or three relays with one pulse. When combined with the DCC Concepts lever switches, which have both passing contacts and two on/off switches (or one to reverse polarity), so these together offer fairly flexible / powerful switching options. Hope that helps but happy to clarify or respond to any other points if wanted. Tony If I may just divert back to my previous post on the subject of using the Gaugemaster relays and in case anyone is minded to try out what I have suggested, I omitted one key detail in terms of how I went about it. When I first used these it was at the suggestion of two guys who were hepling me with the layout at the time, and they had considerable experience in using these in the way that I was proposing. What they told me was that the relays worked more consistently and reliably if two resistors on the relay circuit board were removed; I have no idea, or can't recall what they said about how they behave without this modification but every one of the 60+ of these relays on my layout has been doctored in this way - see image. The two black wires to the right have replaced two resistors that come built into each relay board and whilst I am certain that this negates any warranty, I can say that (touch wood) all of those that I have installed are continuing to work well and I have so far had no failures. I give no warranty to those either following or ignoring my advice!😁 Tony 2 1 2 Link to post Share on other sites More sharing options...

I use them as they can be mounted somewhere accessible unlike Peco's own switches or micro switches which are attached to the point motor, mine are in the control box. 2 1 2 Link to post Share on other sites More sharing options...

Yes, some of mine are close to the pointwork, e.g. those used for polarity switching. whilst there is a bank of them inside the control panel fro such things as changing panel light indications - but anywhere from the trigger switch to the device they are mimicking works fine.

Flying Fox 34F Posted November 8, 2023 Share Posted November 8, 2023 Mike, The sliding door would have to built further out to clear any external framing, so the framing was provided internally. Now why all the framing isn’t internal is unusual, but probably related to vehicle capacity. Look at this way, we’ve ended up with a nice quirky van!

Standard late Midland / LMS arrangement - nothing quirky to it. As @Flying Fox 34F wrote as I was typing (I've started so I'll finish), the right hand side has to be free of projections to allow the door to slide across it. 5 1 1 4 Link to post Share on other sites More sharing options...

LNER4479 Posted November 10, 2023 Author Share Posted November 10, 2023 Yes, but ... Practicalities come into play with my Upperby roundhouse. It is in the corner of the room and will not be easily accessible. Exact positioning of a largely wheelbase loco on the 'table will not be easy, so some latitude is essential if we are not going to forever be stopping the layout to retrieve locos that have been derailed by the movement of the table, caught other locos stabled as they spin round, etc. In contrast, the lengths of the stalls will be as shorter - basically, the instruction will be to buffer up a large loco against the shed wall - so the overall footprint will actually be smaller that the real thing. An overhead camera / screen is envisaged to aid use. It's (allegedly) 90ft in HO which is 79(-ish) ft in OO so not too bad. Other turntables on the layout, that are more accessible will be to scale length. 11 Link to post Share on other sites More sharing options...
