Union Pacific SD40-2

includes SD40T-2, SD45T-2

Note about unit type. UP apparently calls anything an SD40-2 even if it began as a SD40-2, SD40T-2 or SD45T-2. I believe that most SP units were rebuilt to SD40-2 standards as they were shopped, rebuilt and repainted. Some SP SD40-2M were rebuilt from SD40 and SD45.
