Re: EWS TMD, N Gauge, Modern Era

Lovely layout, Tractor Matt Just one thing from a prototypical highway-design perspective, and I think worth serious consideration as you are doing such a good job of capturing the modern industrial ambience: http://i1237.photobucket.com/albums/ff476/TractorMatt/28122010223.jpg I'm not sure which pa...

Re: Control panel LED brightness and related queries

I have been poking the internet to find Cat5 cable specs: apparently a single strand is Ø0.5mm, 0.2mm² and rated for 0.6A. No mention of voltage limits there but Power over Ethernet specs say 37V-57V. That sounds okay to me for carrying bursts of power from the CDU to the point motor and constant LE...

Re: Thomas goes to Africa

Holy thread resurrection, Batman! After rather too much working away from home my return is imminent. In the interests of balance I cannot spend all my time gardening and DIYing so this darn layout needs to get started. We had the trains out at Christmas... http://lh6.ggpht.com/_V-jLA_9de7Q/TGqLYeuO...

Re: Control panel LED brightness and related queries

An elegant solution, Flashbang (I have yet to see an inelegant one from you, to be honest). I hope that my execution can do it justice. On the wire gauges: 24/0.2mm: is that 24 strands of Ø0.2mm or 24 strands of 0.2mm². I am more used to wire being specified in terms of conductor cross-section, e.g....

Re: Control panel LED brightness and related queries

Thanks to both of you. The question about resistors on 12v power to 12v LEDs was because I have seen some people use the term "current limiting" in the LED/resistor context, whereas in my mind "voltage drop" would be more appropriate. I am also erring on the side of seperate PSUs...

Control panel LED brightness and related queries

I am at the procurement stage for control panel equipment and need some advice on LED brightness and viewing angles: I am thinking of 5mm 12V blue LEDs in a blue pin-stripe line diagram to indicate point positions. For best visibility in a well-lit room would you choose 800mcd/120° or 3000mcd/25°? W...

Re: LED...Big style?

look at some of the tamiya RC spares... the lunchbox has 19mm headlamp glasses (Just checked mine) then make a reflector to fit behind it Did you have to mention Tamiya RC monster trucks? I've barely made a start on this model railway lark and you start derailing my train of thought... As you were...

Re: Wanted - Viaduct - Cotswold Area

Are you looking for something prototypical or just an example of a structure in Cotswold-type stone? I am more familiar with the southern edge of the Cotswolds and can't think of any viaducts offhand; but you could always turn one of these upside down, as it were: Dundas on Wikipedia and Google Imag...

Re: Depot style track plan

Coming in a bit late here with my quids worth (I believe it used to be tuppence?). There was another thread talking about small layouts, and there was a link to shunting puzzles . This combines small layouts with operational interest. I'm thinking of having a go at one by way of practicing/testing t...

Thomas goes to Africa

Due to practical constraints (build another house to let, rather than convert the attic for trains) my initial plan has been scaled back to an 8' x 4' base board with trackplan based on the Hornby Thomas and Percy trackmat with a third "mainline" loop and more sidings. What are your though...

Re: The unholy offspring of Brunel, Rhodes and the GNR

Having ascended the learning curve of XTrkCAD I am pleased to report that I have removed my crampons and put down the oxygen bottle. Here is my vision of the first stage of railway development in the recently formed monarchy of Knottswana: http://lh4.ggpht.com/_V-jLA_9de7Q/StCaPiIlt-I/AAAAAAAABzU/Oh...

Re: The unholy offspring of Brunel, Rhodes and the GNR

from the same area For a minute I was thinking "Crikey, what are the chances of somebody else modelling African rail?" Then I saw where you're from. I do like the style of your layout - all that blue and yellow paintwork! Isn't it great how the 125/HST is still going strong. What is the l...

The unholy offspring of Brunel, Rhodes and the GNR

Right, having introduced myself over here it's time to throw my hat into the ring with my early ideas to see what constructive criticism you lot can come up with. The aim of the railway is to try and give our children and me a hobby we can share, and to expose them to ideas and skills like my parent...
