CSXT SD70MAC 4817 was found on the London test track on October 09, 2004.
locomotive production started in the early 1990s. Many variants of the
SD70 have been built over the years, with some still available today.
Consider the SD70I, SD70AC, SD70M, SD70M-2, SD70MAC, SD70ACe,
SD70ACe-T4, SD70ACU,......., and the list continues. Today's photos
allow us to compare and contrast two CSX SD70 variants which were under
test at or near the London plant in 2004.
Some testing for GMD was conducted in the yard at Stratford, Ontario, a short trip northeast of the plant along the Guelph Subdivision. CSXT 4847, model SD70ACe, was photographed on October 12, 2004.
