One of the key design elements of the AMRS modular layout is downtown Austin, Texas. We aren't modelling an exact point in time; the track plan is roughly based on the 1935 arrangement (see the CAD drawing at the bottom of the page), though the buildings and rolling stock will mostly reflect the time period between 1950 and 1975.
At our July 18, 2020 meeting, President Riley Triggs gave a presentation about the railroads in downtown Austin during that time frame:
Here are the materials that Riley used in the presentation:
Presentation Slides (27MB)
Austin Railroad Pictures ca. 1981 (204MB) by Gary Phelps
The Katy Yard at Austin (16MB) from Prototype Modeler, January 1983
SP Operations in Central Texas, Part 1 (3MB) Part 2 (3MB) from SP Mainline, Spring 2019
Street Running in Austin (1MB) from Model Railroader, February 1969
And other links that were referenced:
Club Vice President David Peterson has also drafted a scale drawing of downtown Austin in around 1935. (North is up; SP (TNO) trackage in green, Katy trackage in purple, Mopac (IGN) trackage in blue.)
