So with three SD60M's and an SD70MAC, what were the odds that the MAC may have led? Turns out it's not a 25% chance. In fact, the odds are next to zero that the MAC was in the lead. BNSF has a policy that if there are AC and DC units mixed on a train, a DC unit must be on the point. If the AC unit was on the point, the engineer could actually burn out the traction motors on the DC units without realizing it from the AC unit on the point. With the DC unit leading, the risk of burning out the traction motors is greatly reduced.
