== History == |
|
|
|
|
|
=== Construction and demonstration === |
|
|
Southern Pacific 1518 was constructed in May 1951 as EMD Demonstrator unit #990.<ref name=":0" /><ref name=":1" /> Its road number 990 was in reference to EMD Engineering Department's project number 15990. It successfully completed numerous demonstration tours for EMD on several railroads before being completely overhauled and subsequently sold to Southern Pacific.<ref name=":0" /><ref name=":1" /> |
|
|
|
|
|
During the overhaul at the ]'s ] shops, the prime mover and electrical cabinet were refurbished, and new wheelsets were installed.<ref name=":37">{{Harvp|Shine|1991|p=9-56, 186}}</ref> |
|
|
|
|
|
=== Delivery and revenue service === |
|
|
When 5308 was delivered to SP shortly thereafter, it was slightly different from all other SD7s in that it was their only SD7 to have dual control stands, a winterization hatch over its forward fan (a rare, early feature for SP at that time, but not entirely unbeknownst to them: several of their ]s and the odd ] also had them), and two single-bell Leslie A-200 horns mounted directly behind the cab atop the roof of the long hood.<ref name=":37" /> |
|
|
|
|
|
Upon delivery, SP added a steam generator inside the short hood, a new radio, and a large "ashcan" signal light on the front of the short hood. As a result of its uniqueness, SP classified 5308 into its own single-unit class, DF-116. SP 5308 entered service at ], and was immediately sent to work on the Southern Pacific's subsidiary the ] alongside the SP's other SD7 locomotives on October 23, 1952, less than two full weeks after ownership had transferred from EMD to Southern Pacific.<ref name=":37" /> |
|
|
|
|
|
In the mid-1950s, SP repainted it in a modification of their famous "Black Widow" paint scheme, adding wings at both ends, signifying dual control stands. It is the SP's only SD7 to ever have feathers painted as such. Around 1959, SP's ubiquitous scarlet and grey "Bloody Nose" scheme was applied, which remains to the current day.<ref name=":37" /> |
|
|
|
|
|
In 1965, 1518 was renumbered, becoming 2715. In the late 60s, the "ashcan" signal light was replaced with a Pyle National sealed-beam Gyralight package.<ref name=":37" /> |
|
|
|
|
|
In 1970, 2715 was repainted without its rear wings but still retained its dual control stands. Sometime between 1970 and 1974, its steam generator and water tank were removed, and in 1974, it was renumbered to 1415. The May 1, 1975, Southern Pacific's roster had redesignated 1415 as a class ES615-2. By that date, the two Leslie A-200s were replaced with a Nathan P3 (right side) and an M5 (left side).<ref name=":37" /> |
|
|
|
|
|
=== Rebuild === |
|
|
By the 1980s, the ], like many railroads, had to decide whether to scrap its first-generation power or rebuild it. Based on the success of the ]'s and ]'s rebuild programs, Southern Pacific sent all 42 of their EMD SD7 locomotives through the General Rehabilitation and Improvement Program (GRIP) process in the SP's own Sacramento shops. The locomotives were stripped to the frame and came out virtually as new units and whatever hadn't been changed on 1415 during previous maintenance work was lost during the upgrade to an ].<ref name=":37" /> |
|
|
|
|
|
The unit received a reconditioned 16-567C block (modified to receive 645E liners, making it a 16-645CE), all-new electrical components and controls upgraded to Dash-2 standards, new traction motors, a full light package on both ends, and a modernized car body with a slight hump behind the cab for the new electrical equipment. Gone were the dual controls, the winterization hatch, the Nathan horns, and dual fuel tanks. The dynamic brake blister remained, but the grids were internally disconnected. It emerged from the shops as SD7R 1518 and was reclassified by the ] as an EF615R-1.<ref>Don Bain, '''', October 1985, p. 33</ref><ref>{{Cite web |title=SP R8 and GRIP, By Model |url=https://utahrails.net/sp/sp-r8-grip-by-model.php |access-date=2024-01-11 |website=utahrails.net}}</ref> |

=== Retirement and preservation === |
|
|
Southern Pacific 1518 served another 17 years before being sidelined in ] due to developing mechanical issues.'''<ref name=":37" />'''<ref>{{Cite web |title=SP Retirements, 1995-1997 |url=https://utahrails.net/sp/sp-retirements-metzger.php |access-date=2023-08-26 |website=utahrails.net}}</ref> Fortunately, when the ] and its parent company ] had merged into ], UP had recognized the historical significance of the locomotive and moved 1518 to their ] in ], to be preserved. |

After spending time in storage, Southern Pacific 1518 was donated in April 2003 to the ] (IRM) where it currently resides. 1518 had not been started since its sidelining in 1997, but a few days after it arrived at the ] where the museum's diesel team had got 1518 restored to operational condition. 1518 has been in operation since then and was running in the 2016 ''Diesel Days Parade of Power''. 1518 had also participated in 2017 and 2018 and has since been occasionally seen on the museum's ''Showcase Weekend'' special event.<ref>{{Cite news |last=Alberston |first=Bob. |title=EMD SD7-SP 1518, A precursor to all engines on rails today |journal=Railfan & Railroad |volume=15 |year=1996 |url=https://books.google.com/books?id=7-1VAAAAMAAJ |page=50}}</ref> |
