California's Railroad to the U.S. 1861 - 1996

Southern Pacific GP35R

6300, 6302-6361

61 units rebuilt

6301 ex6630 was rebuilt instead as #4160

In 1977 SP rebuilt one GP35 ex6553 nee7441 as #6300. Then prepared drawings and specifications for Contract rebuilders to rebuild a further 60:

• EF425-R01 - 6300 by Southern Pacific = 1 unit
• EF425-K01 - 6302-6323 by Morrison-Knudsen = 22 units
• EF425-N01 - 6324-6352 by Canadian National = 29 units
• EF425-K01 - 6353-6361 by Morrison-Knudsen = 9 units

These were all SP units, no SSW units were involved.

All these units were rebuilt in kind, retaining their turbo-supercharged 567's, but having the latest 645 compatible engine assemblies fitted.

Any that did not have SP 5-light packages both fore and aft had them applied.

The MK rebuilt units had a different nose 'red-wing' shape and non-standard numberboard numbers, the CN rebuilt units were exactly as per SP standards.

Although the 6300's traveled all over the SP system, their assigned maintenance base was Houston.
