Overview

Total of 1,427 SD70M units (1,452 including the 25 ex SP units)

Beginning in April 2000, to fulfill the delivery schedule for the 1,000 SD70Ms in 2000, EMD spread the workload among three locations:

Of the units assembled in Canada, some units were sent for final painting to VMV Enterprises in Paducah, Kentucky, and to Coast Engine & Equipment (CEECO) in Tacoma, Washington. Units shipped to CEECO were in gray primer paint and were identified with GMDX 1000 series road numbers.

GMLG = General Motors Locomotive Group.

Formal name of EMD's assembly contractor in Mexico is Bombardier Inc., Domicilio Conocido s/n CD Sahagun, Mexico (BTM).

As of February 2005, the last Union Pacific EMD SD70M was officially delivered. With the FRA's Tier II Emissions mandate for locomotives built after January 2005, EMD started delivering the Tier II emissions compliant SD70ACe, which replaced the SD70M.

The new Tier II compliant locomotive for Union Pacific, the SD70ACe, began delivery in January 2005, numbered as UP 8309; deliveries continued to include UP 8823 delivered in March 2013.

SD70M Press Release

From a Union Pacific news release dated March 30, 2000:

SD70M Production on Schedule -- First Unit Expected in April

Production of the SD70Ms at EMD-London is proceeding on schedule, with the first of the 1,000-unit order scheduled to be delivered the last week of April, said Mike Iden, general director- locomotive engineering and quality.

The first unit, number UP 4000, underwent final tests March 23. "Units 2 through 9 are in the assembly lines," Iden said. "Numbers 2-5 are near-complete, 6-9 are platforms in various states of assembly. Cabs through unit 19 are assembled.

"Production is still on-schedule for delivery of the first five units during the last week of April," he said.

With EMD production under way, UP began making weekly inspections at London, including certification of all EMD test procedures for voice radios, event recorders and cab signals, Iden said.

"There were several specification compliance issues identified during visits, but no major issues," he said. "All variations were corrected. We also have identified several design changes with positive benefit to reliability and, in some cases, manufacturing efficiency, all of which are being processed with EMD."

Iden said an SD70M Integrated Service Team was formed, consisting of representatives from UP, EMD, Wabtec, and Harmon and Dayton-Phoenix. "They will focus specifically on SD70M reliability, availability, maintainability and parts issues on a daily basis in a proactive, quick-response manner," he said.

The team's overall goals are to: maintain availability at the required 93-95 percent level; address long-term reliability issues; address SD70M shop counts and dead-in-consist with UPRR shop management and Harriman Dispatching Center personnel; manage parts support to avoid deficiencies and units-held; manage warranty parts handling; and make SD70M maintenance proactive.

"All four suppliers readily and enthusiastically supported establishing the team," Iden said. "They all agreed to have each team member enter Six Sigma training so all have the same set of statistical analysis and root cause tools."

As of June 2004, UP had 1,454 SD70Ms, numbered from 3778 to 5231, including 25 ex SP units numbered UP 3974-3984, 3986-3999 (leaving an empty slot for UP's steam 4-6-6-4 3985).
