I have West End in my B&O library, and it covers only the West End itself, i.e. the mainline from Grafton to Keyser. The scanned image above from SW Pennsylvania is incredible by the way, a wealth of info i never had! But West End covers only the construction and towns along the main, and next to nothing about the origin of the traffic (The M&K branch, which generated 350+ loads a day, is only mentioned, and there isnt any map of it). The West End is an incredible book, but not much help here.
I figured that the coal originated from the Fairmont-Phillippi field, but coal mines today in that region are fairly scarce, and information on the mines and branches themselves is likewise scarce. I believe the Pleasant Creek Trestle was built to accomidate such a branch (the bridge is still extant, and i believe SOME traffic still goes that way) but the Barbour-Taylor county area dosent seem to be anywhere near as well documented as, say, the New River region of C&O's country.
My original plan was to one day have a West End layout...but actual industry along there is very thin. It was a HEAVY traffic route, and in truth, is probably too big for my tastes (i marvel at people that model even larger roads, like PRR or UP-i dont know how you guys do that!) I want to model a mining region, complete with winding branchlines into out of the way places, mine runs to tipples, and most of all, all the coal towns that are rapidly dissapearing back into the WV wilderness. I may indeed switch to a C&O branch theme, such as the laurel branch, or maybe Piney Creek, etc, as not only is that the type of modelling i want to do, they actually used mallets for their mine runs (2-6-6-2s, which is fine. I dont like the Allegheny, i doubt i ever will!) where the B&O usually used connies or mikes (i just like mallets!)
Or, i may just concentrate on B&O...my B&O library is huge (72 volumes at last count-hate to have all that material be for naught). Either way, the map of SW PA shows the density of shippers that region once had, which helps explain some of the enourmous amount of coal that B&O moved. I am sure that the branches in the Grafton-Phillippi-Fairmont area were as productive, and that a map is available. It seems i will just need to keep looking, and thankfully i do enjoy the research!
As far as W.M., i thought that they brought coal from the Elkins region and moved it, via their own tracks, to Hagerstown or Cumberland-did WM have an interchange with B&O in Grafton?
Probably putting way more thought into all of this than is required, Tim
