Well rather than transfer it all I thought I'd just link to the old pages to start with.

Hi Paul,

Good to see those pics up again.

Was the second to last one taken at Romsey?

 

Cheers,

 

Dave

Was the second to last one taken at Romsey?

 

Yes it was, took quite a few there, presently installing signals and a couple of minor scenic alterations before Tolworth.

[samkiller42]

The layout looks very very impressive, looks great.

Thanks for fixing the link on signalling, I'll need it one day, and by then I'll have forgotten how to search the old site.

There was one bit I felt needed some reworking so as the next show is approaching it gave me the impetus to get on and do it.

I wasn't happy with the rocks behind the station carpark as they were too uniform and made a straight wall so i decided to cut some out to break up the wall.

This is what it looked like originally

 

Then I cut out a couple of areas . .

 

 

 

it's now sceniced again ready for the next outing.

Great stuff there! :icon_thumbsup2: The only downside to Bemo H0m scale RhB stock is that it is hideously expensive...

Rhätia at Tolworth

Pics corrupted so edited out.

Well the working signals project creeps forward.

2 of the 3 boards that need rewiring are finished and the control panel fascia has been redone. One more board to rewire then Kevin will start installing the logic circuits. Hopefully have it all in and working in time for the shows in the later half of this year. At least the power to the track worked fine after the rewiring!

One of the signals with the aspects being tested, (you would never see this combination in real life)

 

Work has started to install a stone abutment for the last signal required.

 

View of the underside of two boards rewired so far showing the L girder framework and using plastic comb binders to hold the wiring now.

Hi Paul, The layout is looking superb, excellent, reminds me so much of Via Mala, perhaps I could see it at some time convenient.

 

Regards

 

Kevin.

[PaulRhB]

perhaps I could see it at some time convenient.

 

 

Sure we can organise something when it's all up again after the next show in Feb. Nigel is coming over to video it and we could make an evening of it.

What speed restriction would that be if adopted?

 

(You'd never see that in real life because the ever-efficient Swiss would have replaced the faulty top bulb before it had a chance to expire! )

[PaulRhB]

Well we got all the signals in for Shepton NG show just one board to rewire and the logic circuitry to go now.

New junction signals.

 

The layout and you can see the station signals too.

 

There are a few issues with the point control that have been going on for some time, with so many to set so we are looking at simplifying it for the operator with a route setting switch. Hopefully to reduce the odd embarassing routing into occupied platforms!

Pics from the Epsom show

First the latest offering from Bemo, one of the NEVA driving trailers. I added a driver and a few passengers before the show and if anyone gets one the best way in is to gently ease apart the coach sides from the chassis and pop in wooden stirrers while you ease the sides apart nearer the ends, out drops the chassis and the drivers position is just clipped into the bodyshell and comes out if persuaded gently.

 

 

A low quality video too

 

 

Now to finish off the signalling by October

[NGT6 1315]

I said it before and I'll say it again - this is seriously good! Who says you cannot run an attractive and efficient railway operation on metre gauge? The Swiss sure prove it is possible.

[PaulRhB]

Well it creeps on with the signalling, after a long period boxed up since the last show as we had been busy on other things the layout went back up last week and finally the logic circuits that control the automatic signalling started to go in. 5 Signals to do and the first two were connected and tested

 

Stop!

 

Track one (green & yellow) with clear signals at the far end so a green on the distant too.

 

Track 3 (green & green) and caution on the distant

 

Next shows are Aldeshot in October 2010 and Warley NEC 2010

[SwissRailPassion]

Hi

Model looking better and better. I must go and see it at the next exhibition.

 

Meanwhile at BERGUN this summer, the old station is being substantially remodelled with a new bay platform and demolition of the goods facilities.

This webcam link shows the devastation in progress. Very glad I took pics on my last visit in Aug 2009.

After some hard work by my electrical genius Kevin all the signals are now fully automated so they not only show the routes but come off as a train approaches and revert to red behind it. Now working on a guide to show what it means to people watching the layout.

 

Couple of shows coming up, Aldershot 9 & 10th October and Warley NEC 20 & 21st November.

 

Lots of questions are asked about the materials used for the layout so I'm now working on some simple info sheets to hand out to anyone really interested at a show to save scribbling things down on scraps of paper.

Here's the first general info sheet, notice RMweb gets a plug

 

[PaulRhB]

Next one is a hopefully simple guide to what the signals actually mean. (modified version following Horsetans valid note below)

 

 

and here are the two main parts of the text, comments welcome.

Main Aspect Head

 

It is the combination of aspects that tell the driver where he is going,

 

see the chart below.

 

 

 

Distant Head, telling driver what to expect on the next signal

 

(may be mounted on a separate post or beneath the main head).

 

Two Yellow aspects means the next signal is showing a Red aspect.

 

Two Green aspects means the next signal is showing a proceed aspect.

 

---

 

A single signal placed beyond points at the exit end of the loops uses the same aspects to tell the driver when they have permission to proceed. e.g. Driver in Track 2 would need a single green aspect as authority to leave the station.

[PaulRhB]

Here are a couple of videos of the signals working at the Aldershot show. Still a couple of minor glitches to sort as the power contacts for the lights in the coaches are confusing the logic circuits a bit and causing the aspects to flash a bit as coaches pass over the block joins.

 

[Horsetan]

......Main Aspect Head

 

It is the combination of aspects that tell the driver where he is going....

 

I was slightly thrown by the example on the chart. I thought a single green usually applied to the main / straight line, and that anything branching off it would be subject to speed-restricted aspects, e.g. double green for Track 2 rather than 3, green + yellow for Track 1?

Good point I'll amend the tracks, serves me right for being lazy and using that picture of three loops!

 

Ok amended diagram for that to reflect how it should have been in the first place! the centre track tends to be the main with loops either side on the RhB.

Generally speaking, this depends on the diverging branch radius of the points and the line speed on the straight route at the relevant place. If the radius is large enough, the diverging speed may be the same as for the straight route, so that the main aspect will be identical. I rather doubt this will be the case anywhere on the RhB network, though.

 

One example from Germany I can think of immediately - though it is standard gauge, of course - would be the points at both sides of the underground suburban section of Frankfurt Central Station, which allow for 60 kph regardless of the route. Meanwhile, with speed signalling as we have it here, you may also encounter illuminated speed indicators co-located with home signals which are configured to be able to display all speeds permitted for each of the routes beyond the signal's location. Let's say we have a line with 120 kph permitted on the straight route and 70 on the diverging route - in this case the home signal will show a plain single green for the straight route and a single green plus a figure "7" speed indication for the diverging route.

 

Furthermore, the green/yellow aspect on home signals may be used for speeds up to 60 kph, but signifies a 40 kph speed restriction when no additional information is given. This can be done by way of said speed indicators if multiple routes with different speeds follow beyond the signal, or by a simple entry in the driver's working timetable. Here in Germany, these timetables traditionally include references to important signals relevant to the train in question, and in many cases you will see these specific references amended by brief indications in the style of "E xx", "A xx" or "Z xx", where "xx" will be a number. An "E 50" indication, for example, will indicate the signal - which serves as a station entry signal in this case - to allow for 50 kph when showing a green/yellow aspect, while a "Z 60" will point out that the home signal serves as an intermediate signal ("Zwischensignal") and allows for 60 kph under a green/yellow aspect. An "A 50" indication, finally, would be an example for a departure signal ("Ausfahrsignal") allowing for 50 kph under a green/yellow aspect.

 

Of course, speed restrictions will usually be given as well when a train is being routed into a partially occupied track or when no sufficient safety overlap can be provided for other reasons.
