L SD70 Conrail Quality NS PRR

SD70 in Conrail Quality color scheme
Performance Specifications:-
4500 HP locomotive equipped with EMD's 16-710G3C-T1 engine
EPA Tier-1 emissions certified
Tractive and braking effort capability
137,000 lbs continuous TE
175,500 lbs starting TE
81,000 lbs braking effort

Performance Impact:-
The SD70 provides unit reduction, fuel savings and additional revenue tonnage capability over SD40-2 locomotives
Train simulation results and actual field demonstrations indicate:
3 SD70's can replace 5 SD40-2's in high tractive effort operations
Operation of fewer units results in significant maintenance and operating savings
