Locomotive Phases - 4-axle EMD Locomotives

.
GP35
Phase 1a1: 7 latched hood doors, short central air intake, 6 louvers on battery boxes, flat dustbin hatch (roof behind cab), flat panel under front headlight, early (barred) radiator intakes, "fishbelly" frame
Phase 1a2: 3 latched hood doors
Phase 1b1: Longer central air intake
Phase 1b2: 7 latched hood doors, bulge under front headlight
Phase 1b3: 2 louvers on left battery box
Phase 1c: late (screened) radiator intakes, 2 louvers on both battery boxes (late Phase 1c)
Phase 1d: raised dustbin hatch
Phase 2a: flat dustbin hatch, straight frame (see resulting differences under "other details" below)
Phase 2b: raised dustbin hatch
Phase 2c: corrugated central air intake

Other details:
--The central radiator fan (36") varies between a flat open-top and a round button-top design.
--The change from a fishbelly frame to a straight frame on Phase 2a GP35's caused several visible differences, including a thinner side frame (especially above the air reservoirs), a taller fuel tank, a marginally higher walkway and new steps.
