2GS14B - FresnoSubber/Fresno-and-Co.-Trainbuild-Tomfuckery GitHub Wiki
The first ever genset built was a 2GS14B, this one. It was the only one of its kind built, as all other 2GS14Bs used the 3GS21B design, minus the 3rd engine. Photo Credit: Paul Rome
The 2GS14B is what kickstarted the genset trend. Using an MP15 core, UPY 2005 was finished in November 2005 and was demonstrated in 2006, where it would later be put to work in the L.A. Area.
Later on, the design would conform to normality, using the 3GS21B design.
UP and CSX were the main notable holders of 2GS14Bs, with 2005 being UP's only unit, and CSX having 4. All others were smaller industrial and shortline railroads.

Notes
(1): Depends on the core unit, which I believe in this case is an MP15, so this is basically the specs for UPY 2005.
(2): Multiply this by 2, as these engines would have more than one generator. Hence the name "genset".
(3): Rating taken from the 572RSL. Also the generator’s 3 phase but like, toast or whoever made the page on the sd70ace pretty much explained that multiplying the values by three is not how it works but whatever. Do what you want.
