No, the Frisco had no EMD GP18's. All the early Frisco EMD road switchers were GP7's. The SLSF did have five ALCo RS-2's as well, SLSF 550-554, which were each ultimately repowered with the EMD 567-C engine. The new engine was mounted in a late phase EMD GP9 hood - which looked like a GP18 hood, but wasn't. The 567-C was rated at up to 1750HP, but the Frisco had them downrated to 1500HP, such that they could be freely mixed in with the GP7 fleet. The GP7's were powered with the 567-B engine, 1500HP. Ken
Steve is correct, though not all of the Frisco GP7's had a steam generator. The Frisco GP7's were numbered SLSF 500-549 and SLSF 555-632. The gap in the middle was due to the RS2's mentioned above. Per Marre & Harper's "Frisco Diesel Power", the following Frisco GP7's came with a steam generator, while all the others did not: SLSF 500-514 SLSF 557-572 SLSF 598-618 Ken
Absolutely! Here's an example on train 101 at Rosedale. The consist has swollen due to an airline strike. http://www.frisco.org/vb/attachment.php?attachmentid=643&d=1129085207
Per Marre/Harper (the Frisco diesel "Bible"), the s/g's were retired in all of the Frisco's s/g equipped GP7's in either 1962 or 1964, and were physically removed from them in early 1967 ..... EXCEPT for units SLSF 598-618. These remained in service until early1968, when they were retired, since passenger service on the Frisco had ceased by then. Ken
Karl That's a really nice photo of 101 -- I have seen very few shots of GP-7's in passenger service after they were painted in the red-and-white scheme. To have it sandwiched between two traditionally-painted E8's is especially nice. Gordon
