- All C30-7A units are Phase 2d.
- Some later C36-7 units featured modified radiator and dynamic brake intakes. Other units are indistinguishable from the C30-7.
- Doors under forward section of radiator may or may not have 3 narrow vertical intakes. Some units had such intakes retrofitted.
- Units rode on 5 FB-3 truck types: Adirondack or GSC castings, with low- or high-mounted brake cylinders, and Adirondack castings with clasp brakes (NW versions).
- Some export Phase 2a through 2d units lack exhaust silencer, but have the larger stack base.
- Conrail units have 3-step end platforms in place of standard 4 steps.
