Looks good, Dave. How far away are you from laying scenery?

Have you thought about using Wordpress for your site? It does things like shrink images (linking to the original), which helps reduce page load times.

Scvenery is ages away, in terms of finished scenes. At the moment there is one tree one platform on the layout. only the re ains of Broughton are ballasted. as shown in this and the last  update there is some basic landform done.

The im still is getting the railway operational. then I ca  enjoy scenery, as I prefer that to track and wiring anyday.

2nd update for May.

http://dth.railpage.org.au/trainroom/updates/up21may2015.htm

this time reduced the pohto size a bit as well.

It turns the throw arm into a electrical switch by soldering the frog wire directly to it. I then get some old PMG relays contacts bend them and screw either side of the throw, making a cride SPST switch

I did this in the staging yard on the Dutton Bay, but eventually swapped it for microswitches. My old DBT page says simply I was "replacing the "dodgy" phosphor bronze wipers with micro-switches" so perhaps it was an adjustment problem, or maybe the phosphor bronze wipers I used at each end of the travel needed to be beefier. Can't remember. It will be interesting to hear how yours work over time.

Agree with you John it is a gamble.  Re using microswitches, so far I have used only one. I may have to try 2, one each side. But on one problem point I have  a micro switch on, it is when the  lever hits the microswitch not quite right that's the problem. the adjustment would be  tiny to get it working properly.

my concern is more re the conductivity of the switchmaster clone arm over time.

Re the wiper arms, thery can be adjusted a bit, so hopefully in  the years to go, if the layout gets photographed  with finished scenery I'll know by then.

I also have to clean the layout up as I will host a few modellers in July. That's the biggest task I have had for a while !

Hi David,

Apologies for hi-jacking your layout thread, but I wanted to ask a sort of Admin question and didn't want to start a new Fred.  Maybe I should have.

Am I the only one who thinks we have too many Announcement and Sticky threads in this Forum?  When I open the Forum, and to be honest it is the only Railpage forum I visit frequently, I have to scroll down a fair way before finding the unread topics.  I would prefer if the unread topics were on the screen rather than a whole lot of stickies.

If everyone else loves the stickies to be on screen I will shut up.

I haven''t suggested (yet) which stickies might be amalgamated with other stickies.  First of all finding the opinion whether you like things as they are.

Best regards,
John

David - out of curiosity, what are your goals for the timetables?  I ask only as I'm more familiar with TT/TO 'style' timetables which show all trains, and they're typically used by lower priority trains to work out whether they can proceed and not interfere with superior trains.  However for that to work, you need to see every train's timetable rather than just your own and any scheduled meets.

For many years I participated with timetable operation  of the Eltham Model Railway Club's former layout at Panton Hill. We had a graph timtable, a master and each station had a   cut down one for each station.

This was the type of timetableI intended to use on my layout. Fellow EMRC member Mark Laildlay added to the system with Train cards with pouches for loco and rollingstock to be shunted. For this I would have to have a lot of planned freight locations, and clearly radable wagon numbers. Att he moment only one station has all it's tack working, and three others in  a wide range of completness

So when I started a timetable for my layout I went the EMRC route with graphs, duly  printed off and hung at each station.


One Christmas I visited Craig Mackie's Casino Layout As well as being a NCE based layout he inspired me on several levels. One was his car card system and electric staff. I decided to try a version  of his system. Eventually I wish to do some car shunting like Mark's version.

At the moment the timetable is identical , the graph and the cards. The guys comming over like the cards and could not easily understand the timetable graph.

I suppose it also depends on how you operate a layout, The ELtham club had fixed people at every staion, and one drove train to the staion and also did all shunting.  Mark has people at the stations who do the shunting, other operators drive the train between stations and the staging yards - but do not fully follow the train.  My layout at the moment is mainly operatoes following the train. Craig had people follow the trains and shunt.


The American TT/TO is rather rare here as a Aussie timetable has all movements on it, and rarely a extra move.


So hope that explains a bit. when  staions get their full track done there will be nmore shunting. But at the moment train running is the thing. I do wish to eventually try a CTC sstem with a CTC operaotr in control of the mainline. There again there will be das where I'll turn that off and use the staff system I'm gradually installing. Yet another day I would like to try dispatching, with all operators radio equiped.

Here's some docco on the present timtable, wel mainly up to date - I have added 4-6 new trains since doing this document.

http://dth.railpage.org.au/trainroom/docs/ttv1.pdf

As may who have done timetables, getting  it right is hard. Rela time and fast time have issues,  as in how long does a train take to leave the staging and get to each staion in turn etc. The present timetable is far to leniant on time. I will have to do more work on a new one next time...

David Head

ps may use thos post ibn a update later on.....  was a good question to get me thinking!

Thanks; those are some very pretty string diagrams.

So sorry if I'm missing something larger, but the timetable largely controls departure times (including meets) to ensure that various yards and/or track sections aren't overloaded?  I'm not completely clear on how the train cards interacts with the timetable, other than possibly that they're bundled together for operators to use?

The TT/TO operation that I'm more familiar with doesn't really require extras (although they can add some interest).  The timetable provides all the the information you need to know about whether you can proceed onto another station based on the class (typically 1-3) of your train and the likely presence (or otherwise) of other trains.  It also requires some minimum form of book keeping at each station to sign in as you arrive and depart and probably a minimum of 5 stations, mostly connected by with single track.

If running with a dispatcher who remembers that we're spending our weekends playing with trains to have fun it can provide quite a entertaining puzzle at times.  If you score a dispatcher who wants to recreate 'what it was really like' it can be less entertaining, which is why it can be a controversial operating scheme Smile.

The train cards were written and produced after doing the graph timetable.The timetable dictates all train movements on the line. The times on the card match the graph so it is the same thing. The graph is useful for the bigger picture, to see where a train crosses, or departs.

It is also on how the layout is used. I and many club are used to reading the timetable to drive a train, but stationn bound, ie every station operator was the signalman and driver TO their station, in driving the train to one you knew where to stop.  The timetable just allowed us to runs lots of trains just following the  a path. It did not promote shunting.

The train cards so, as I can put in instructions for the train operator to do. In future the train cards will be folders, much like what Mark has, in you add any wagons to shunt, and the loco card. That won't happen for a while on my layout. But it will mean a train can run and shunt specifically.

It is a work in progress. One day I'd like to see the TT/TO tried. But will need a good teacher !

The "train cards" describe the job to be done by each train number.  The timetable data on the card is extracted from the data that the train graph is drawn from.  It includes station names and times or arrival and departure at each and information on what is done at each station.  The card has a pocket which hold the loco card and the truck cards.  The truck cards have a pocket which has 4 instructions (two each side facing each way).

text only update today.

Made a new programming track just sitting behind the computer monitor in the main room, on a shelf. 4ft long I have also out in a switch so I can use it as the program track, or a running track, for testing. Track cannot be connected to layout.  Now I can program the loco and test.  It worls out a lot better.

Hi David - to some extent, I think my preference would depend on the conventions you've used elsewhere in the layout.

To me, the single LED is a bit more prototypical (matches the controls and track side switch stand indications) but tends to be less intuitive for operators as 'reverse' and 'normal' aren't consistent with regards to the actual track geometry.  What I mean by this is that sometimes normal is the straight route and sometimes the diverging. Personally I'd consider adding a green or red dot to the right of the R and N on the panel diagram to make it clear which is which at a glance, although that will probably work better on a (relatively larger) physical panel than a (relatively smaller) electronic display.  With that addition, and not knowing how your controls etc. are setup elsewhere, the single LED would be my preference.

If you go the two LED route, I don't know if I'd bother with bicolour LEDs; I'd just have two green LEDs (the red isn't adding any more information unless the green LEDs are difficult to see in the room).  It's definitely easier to read but seems more something you'd find in a model than the prototype, at least to me.
