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