Remember the Coal Belt region in the western Arkansas region had three major railroads penetrating it: The Frisco, the Midland Valley, and the St. Louis, Iron Mountain & Southern. (WHICH, by the way, I have almost ALL track complete in the Coal Belt region for all of these railroads... AND... enough Rock Island RR track at towns to have effective interchange and AI traffic potential! Eat your heart's out. )
ANYWAY... back to the current topic at hand...
Below you'll find a couple of AE maps depicting the Frisco's Mansfield Branch between Jenson and Mansfield. Most major points, and what have you, are noted on the maps themselves. What the maps don't show is the hill n' dale nature of the line, as well as the grades present on some of the coal spurs/branches. The grades aren't terribly severe... but I do recall laying grades over 2% at some of the mines when I was laying rail. Try getting a heavy cut of gondolas loaded with coal up out of a hole like that! (Or getting them down the grade safely with 1900's era air brakes!)
Also, Jenson was noted to have simplistic engine service facilities as well as a modest yard for empties in/loads out to the north/south Frisco main line. It was also recorded that during the 1900's era the Mansfield Branch kept five full crews busy out on the line daily. That's a bunch of mine traffic for a 17.9 mile branch. Oh... and the Rock Island had trackage rights over the line to Fort Smith to the tune of four trains a day. In fact, there were EIGHT scheduled passenger trains a day on this line in the 1900's! Add to this mix the five coal switchers plying the line and working the spurs, along with any extras to/from Fort Smith to Mansfield... and there's a bit of traffic potential in this one lil' segment of railroad!!
Anyway... this is what I have been piddling with when not trying to learn 3D Canvas. For example, last night I completed the updates around Montreal. There are now two more significant mines at Montreal that I learned about the past few months!
All for now... talk to you later!!
