Two of the newest locomotives on the NS roster, EMD SD70ACe 1099 and 1098, lead an older SD70 on southbound train Q8E just south of Luttrell, TN enroute from Middlesboro, KY to Knoxville, TN. At the time of this photo these two engines were in their third day in revenue service after having been setup in Chattnooga earlier in the week following delivery from Mexico.
