The Black Water Junction (BWJ) yard and the adjoining town of Kirksville are usually the busiest areas in a typical operating session, so the highest paid workers (the best of the best) are often assigned here.  All through trains stop here, as well as locals to and from Lodestone and Truckee.  A total of 10 industries reside here, with a total of 24 spots.  The yard contains additional spots for 30 cars, and the nearby Hogscald Interchange holds 20 cars.   

During 4 interchange operation, this area is the responsibility of the Lodestone, Sierra, and Incline Village Railroad (LS&I).  One employee switches Black Water and Kirksville, while another makes a run up to Truckee and Lodestone to service those industries.
