Hopefully the last Design! Design 3.7! The changes to this one include the platform crossover at station one changing the platform crossover's directions to match the entering crossover. The only other change, after much debate is changing the Diamond to a single slip. I am adverse to slips on the main and it was very very very rare in NSW railways, even in the 60s (please correct me if I am wrong in this). The only locations this occurred (as far as I'm aware) was Central, Strathfield, and Hornsby. The Hornsby slip was short lived and I worked on the replacement slip in 2012 and the original slip was made into turnouts and crossovers decades ago.
I decided to change the crossover to ease the running of the suburban train; 4 FO and a 46. The Set comes in on the Up main, over the crossover to platform 1, the 46 runs round and the set leaves on the Down Main. Or alternatively (with the Single slip) depart from platform 2 just as easily. Now the Slip. I didn't like the slip due to inherit speed restrictions associated with a slip. For example, a goods leaving the yard cannot increase speed through a double slip until the last car has left the slip. Whereas a diamond does not have this restriction. I feel the single slip allows me in the Down direction no speed restriction and in the |
Up direction speed restrictions don't matter. I haven't scarified my yard operation functionality or practicality and I have achieved more operations. I will think more on the double slips however I hope this doesn't change as simplification is always better (I do not look forward to the overheads associated with the slip, as I have done in the 1:1 scale railways and it's.... difficult in the best circumstances).
Base Board Design
Now to the base board design. So my limit factors here:
1. Door Measurement - Door is 780mm wide and I want to avoid putting the panels on their sides during transport
2. Ute Tub - The ute tub is approximately 1400 by 1300 with wheel arches of 2 180 x 750mm leaving 1400 x 940 in the base and then expanding to the 1400 x 1300

So here's the plan, each panel will be a maximum of 700mm wide and 1400mm long with a cover over the top giving the overall height of the panel and cover to be 250mm. The diagram has measurements in centimetre (so for those not verse in the metric system add a 0 to the end of each measurement for millimetres). I have made the layout into 11 primary panels and 3 secondary panels that will have limited detail and not require covers. The idea behind these panels are to |
allow me to move the layout myself (and thus make the layout more permanent or at least more lasting). Should we move house parts of the layout will be salvageable where need be depending on the size of the room. The only other issue at this stage with this moving of the panels (if a move is required) is the structures. Model buildings are, in general, about 100mm, plus any Styrofoam, tall and then the 100m of base boards. Therefore any building over 100mm will have to not be glued down. For items like the wheat silo the decision is easy, but for other buildings it will have to be a case by case basis.
I'm fairly satisfied with this plan of attack. In my next blog I hope to go into possible signals and soon after start my first construction blog on either construction methods of the overhead staunchens or the first construction of the first panel. Progress in the planning has been made and soon it will be time to put the pen down and pick up the tools!
