Up Staging Yard changes …
Every so often, I open up my listing of trains I am modelling and add more information to the spread sheet where I calculate model train lengths and tonnage.
The longest trains that will run on the layout are the Up block wheat and coal, and all of these have four locos up front, with generally two of these being the bank engines.
I was always hoping to be able to run prototypical length trains, but found I had an issue with the road lengths in the Up Staging.
The original design of the Up Staging had the following standing room lengths (in mm) for trains:
5400; 4340; 4200; 3570; 3500; 3500; 2790; 2790.
Currently my four longest trains (to prototypical length & tonnage) are:
Up Wheat, Quad locos + 26 x WTY + brakevan = 5280mm
Up Wheat, Quad locos + 26 x WTY + brakevan = 5260mm
Up Coal, Quad locos + 21 x CHS + brakevan x 2 = 4910mm
Up Coal, Quad locos + 21 x CHS + brakevan = 4800mm
As can be seen, there was no way I was going to be able to fit these trains into the four longest roads.
In hindsight, I should have made the Up yards much longer than the Down yards, but instead made them roughly equal lengths.
So to accommodate the long trains, I have decided to rebuild the Up yards using 3-way turnouts in certain locations to lengthen the roads. I will only have to build three new 3-way turnouts.
The revised Up Staging now gives me the following standing room lengths in mm:
5495; 5080; 5060; 4765; 4310; 4070; 4030; 4020.
On one of the wheat trains, I may have to drop up to two wagons, and on one of the coal trains, one wagon. This will still give me near prototypical length trains.
The drawing above shows the differences between the old and new yard design. The majority of roads are now significantly longer than in the old design.
