U28C
Dates Built: Feb.1966 to Nov.1966
Number Built: 81
The U28C was a development of the U25C with a power increase of 300HP.
Phase Ia: Externally identical to the late (phase IIIb) U25C.
Built Dates: Feb. 1966
Number Built: 2 (CB&Q #562-563)
Phase Ib: Handrail stanchions changed to a pressed steel type.
Built Dates: Apr. to July 1966
Number Built: 12 (NP #2800-2811)
Phase Ic: Windshield changed to a two-piece.
Built Dates: March to April 1966
Number Built: 14 (CB&Q #564-577)
Phase II: Competely redesigned car-body.
a: Air tanks moved to the ends of the fuel tank.
b: Air intake section added behind cab.
c: Walkway over Radiator.
d: Protruding intake section under the radiator.
e: Raised section of rear walkway disappears.
f: Trucks changed to a new style.**
g: Shape of fuel tank changes, vertical sides are not as deep.
h: Steam generator available. (U28CG)
Built Dates: May to Nov.1966
Number Built: 53 (L&N #1526-1533)
(PRR #6520-6534)
(SP #7150-7159)
(UP #2800-2809)
(ATSF #350-359)*
Notes: * Santa Fe units built as U28CGs.
** U28C phase II's came with three styles of trucks. Two were supplied by Adirondack Steel Castings. The earlier verison (AD-1) had a distinctive "eyebrow" over the center journal, whereas the later version (AD-2) featured a straight frame with distinct humps over each journal. Two holes, one near each outboard journal, further distinguish this design.
The third design was supplied by General Steel Casting (GSC-1), it is distinguished by an arched side frame similar to EMD's flexicoil truck. Three round holes appear in the side frame, one above the center axle and one each in the arch between the axles.
Side Note: You'll want to go by photographic evidence when choosing which truck to use when modeling. I've seen photos of the same locomotive which had different types of trucks at various times in it's life. I've also seen photos where a locomotive has two different types of trucks at the same time.
Enjoy, Dan
