Seniority Districts for Engineers on the C-S used to correspond to the three operating districts when a Southern Railway property. Recently saw a photo of #229 coming across the Cumberland River and the caption stated the train was approaching a crew change at Burnside. I was aware that Middle District crews went thru to Emory Gap instead of Oakdale, although don't know what date this change occurred. Are two crews running off the mileage now between Gest Street and the Wye @ at Citico?
