hi there, love the layout, i like to see my trains run around, and the elevation, always wanted to try that....more details please. also do you have a name...i don't quite get the use of sobriquets on the forum...or god forbid avatars...what are we.... 12? cheers patrick michael mary (yes!) mac namara

thanks

just checking guys, is the bray wheelers swapmeet/sale still on next sunday? cheers paddy mac

Hi all, and many thanks for all the help. I would like to acknowledge the generosity of spirit shown by members of this community, for your time in responding and sharing of your knowledge. I remember only a couple of years ago, wrenneire (dave?) you gave me some track for free, and very useful it was too. I'm at this about 12 years now and on my 4th layout, but still so many skills to learn and master. cheers guys (no gals on the forum...i'm not sure)

sorted, looked at some photos online, dirty grey with lots of weathering seems to the answer

i have several of these cattle wagons, any suggestions for colour of body and roof?

some great suggestions there lads and fab work on the respray jobs. wrennery, yes i would be interested where is the bray wheelers gig on cheers paddy mac

thanks for all the replies/advice it'll take me a while to consider, thanks again paddy

thanks Fran, no shame trying to earn a living.

Hi all, any ideas for where i can get irish wagons etc for my layout, or even hornby/dapol/bachmann stuff that wouldn't look to out of place. i'm flexible on the era, 70's ,80's, 90's. not kits though. RTR cheers paddy mac

cheers rob, track is Hornby, painted with acrylic "burnt umber", of course no ballasting done yet, i have so much track i'm not looking forward to that job

Plaster is usually white when fully dry.

A lot more detail added to station throat. Warehouse building is using templates and brick paper from card kit download. Blue warehouse cladding is corrugated paper painted, well, blue, inspiration for this colour is from loco cleaning building in Heuston station. I’ve shown some of the stages in the production of the card model, which will be old news to most of you, but I hope will be of interest to newer modellers. Fencing around warehouse is made with car repair mesh from Halfords, and those really thick long matches. So where am I going with all this, you might ask….or not. Originally, I wasn’t intending on having a road overbridge here, just the cutting. But I commute to Dublin Heuston and look out the window… a lot, and there is a road overbridge on the way in, so I thought why not, and it gives a scenic break to the flatness of the layout, and I think we all like to see our trains appear from under a bridge. On the way into Heuston there are offices close to the railway line at Inchicore and this is the inspiration for the warehouse. So, the layout has morphed into a 4 track through station like Celbridge with a taste of the complexity of track and industrial/commercial activity on the way into Heuston. On the south side of Celbridge we have fields and on the north side a golf course, so not a whole lot to model. Although I’ve never seen a golf course modelled….so maybe next time.

i meant on the emabankment?

sorry.....i meant track plan....that we could see...

like it, is that modelling clay?

like it pat, you sure made a lot of buildings, with card i presume? great work and looks like you have a nice bit of space, have you a track that we could see? cheers paddy mac

thanks for likes guys. must do better quality photos next time

Some progress on scenic work at station throat, still a lot more detail to add.

cheers

As promised some detail on the circuit used in the most recent video on “Celbridge” As before my test track is not actually an X crossing but the two parallel tracks simulate what I want to do. Track 1 is the main-line thru the junction and the reed switches are here. Track 2 is the “suburban” line and is required to wait for the main-line to pass thru the X crossing, this track is isolated either side of the X crossing. R1 is the reed switch that detects the loco as it approaches the “X crossing” R2 is the reed switch as it leaves the “X crossing” junction. The isolated section on track 2 (the one I want to shut down) is connected to the relay thru the common (cm) and normally closed (nc) pins. So the isolated section is live at the beginning of the sequence. When R1 is activated by magnet on loco it closes and delivers power to coil 1 on the relay, this causes relay to open the cm/nc circuit and so power is cut off to the isolated section on track 2. Because this is a latching relay we only need one pulse to coil 1 and the cm/nc remains open. (it doesn’t matter that R1 opens again once the loco moves away, once “latched” it stays latched). Coil 2 un-latches the relay. So once the loco passes over R2 it activates coil 2 which unlatches the relay so the cm/nc circuit reverts to it original state and power is returned to isolated section on track 2. As noted before this is a WIP and a learning curve, I am working on solutions to problems such as what if the loco on the suburban line is in the middle of X crossing as loco on mainline approaches….watch this space.

thanks, was on the site couldn't get info on what size the OO gauge magnet is?

What happens.....crash bang multiple casualties... Its still very much a work in progress, and learning what sensors work best and easiest. So when i actually use it on the layout i'll probably have another reed switch on the junction, and if junction is occupied i'll cut power to mainline, will probably need to get into some Arduino work then, unless i can get away with just using some kind of logic circuit.....so more research to do

thanks, been a bit of trial and error with magnets, got 8mm dia ones and they were too small, the one in the photo is 25mm and 3 mm thick and it fouls on the track with my 141's....d'oh 16 mm gauge. I want to get one small enough, but strong enough as i may locate reed switches beside track not under it. cheers paddy mac

The next chapter in my efforts to control trains thru the diamond crossing. This is a photo of actual X crossing on the layout. The green loco is on the mainline which has priority, the red loco is on the commuter line, I want to cut power to this line when the mainline is coming thru. I’ve made up a test twin track board to…. well test it. This time I’m using reed switches to detect position of the train, switches are activated by magnet attached to the loco, see photo. And the control is via a “Latching” relay. Main improvements over last attempt is the simplicity of the system with reed switches as opposed to the light sensors, as discussed before. Also my “discovery” of the latching relay means once the train is detected it stays detected, until the next reed switch is activated. Photos and video below. I’ll give more detail and a circuit diagram over on the Electronics forum. And the video
