General Notes:

  1. UP 7336-7405 were renumbered from UP 7010-7079, which were assigned UP 7336-7405 in the December 1999 renumber plan; 30 units renumbered between June 2000 and September 2005; those 30 units are to be renumbered (out of sequence) back to the 7010 series to clear the 7300 series for additional new units from GE (UP 7377 was the first, renumbered to UP 7011 (2nd) on August 1, 2008).
  2. UP 7336-7338 were ordered as UP 7080-7082, but were delivered as UP 7010-7012; the 7010-7012 number group was originally assigned to a canceled order for three SP C60AC units (assigned SP numbers 600-602).
  3. The UP designation for these locomotives is both C44/60AC and C6044AC; GE designation is AC6000 Convertible; AC6000CW is displayed on builder's plate. (information from Norm Metcalf)
  4. UP 7344 (ex UP 7018) was the first unit in this group to be renumbered, completed on 30 June 2000; UP 7390 was the last, completed on 1 September 2005.
