Original Layout Design Notes
The original design was intended to provide an interesting layout to
operate and view in a 9' by 5' space. I decided on three primary requirements
to this design.
- Continuous running
- A passing siding
- A way to reverse direction (either loop or wye)
In addition, I wanted to provide a way to expand the layout for longer
continuous running and to provide for yards.
The design I ended up with provided all of these features, but several
compromises had to be made.
- 18" radius curves are used
- Atlas Snap switches are used (equivalent to about 4 1/2)
- Steep grades - about 4%
The end effect of this is that I am pretty limited in the size of trains
that I can run. I can only run about 6 to 8 cars per locomotive, without
adding help on uphill grades. Also the snap switches and 18" radius curves
limit the size of locomotives and rolling stock that I can comfortably run.
The passing side will hold about 11 or 12 cars, so that is about the maximum
length train that I typically run. I have implemented 2 industries on
this layout. A gravel crushing plant and a stone cutting plant. Also there
is "Johnstown Station" and the nearby milk stop.
Model Railroad Has Been Torn Down
My model railroad no longer exists. It has been torn down in order
to provide space for other activities. Trains and structures are safely
packed away for another day.
