Making her second pass under the block signals at Pasis Jct., Ontario, in less than five hours, BNSF 794 leads CN train 399 westward into the setting sun. Earlier, BNSF 794 had been sandwiched between a pair of WC 6900's eastbound on CN train 148, however 399 ran into trouble between Bayview and Copetown when it's leader, CN 5667, failed. With good tonnage and only BNSF 6946 to do the work on 399, the decision was made to have BNSF 794 taken off 148, placed in trailing position on 399, wye the power at Bayview so BNSF 794 would become the leader and the sticken CN 5667 a frozen paperweight. 1615hrs.
