Some of my favorite engines, like the GP39-2, aren't represented by the Southern Railway, Clinchfield Railroad, or the Chessie system (as someone pointed out to me, the C&O/Chessie did have GP39s, but not GP39-2s), so I include them in the Blue Creek engine roster.
 
For the mid-60s Blue Creek operating scheme, the BCRR primarily uses it's own motive power, drawn from a roster of a handful of 4-axle diesel engines, some aging, some new.  These engines will be represented by FA1/FB1 #100, GP7 #701, and GP20 #204.
 
For the mid-'80s Blue Creek operating scheme, the BCRR uses both it's own motive power, and leased motive power from other railroads.  GP39-2 #396 will represent later Blue Creek home power, while engines like TCC GP15 #513 from other roads will fill out the power requirements.
