The Jefferson Historical Society and Museum now have the R.D. Moses T&P Model Railroad displayed at the Museum. See www.jeffersonmuseum.com.
The L&A/KCS line that runs through Jefferson once came up from Waskom,Tx. You can barely see the old grade in some spots along I-20 between Shreveport and Greenwood. On historical topos I traced the line from Greenwood/Waskom to Karnack, Tx. Appears that when I-20 was built the KCS rerouted the line to Jefferson from Blanchard, La. Looks like I-20 through Shreveport runs on the ROW where the line used to be.
