C36 7 - MagnumMacKivler/RLCPT2 GitHub Wiki
Conrail 6621, contributed by Andrew Konigsberg. rrpicturearchives.net.
The C36-7 is an iterative improvement on the U36C. The model is functionally identical to the C30-7 with an unreliable spotting mark of larger rear air intakes under the radiator on late models, visible in-photo. The model was introduced two years after the C30-7 and as such, domestic sales suffered; of 599 units produced, the vast majority were sent to China.
Mechanically, the unit is identical to the C30-7 as well, however features an uprated generator model and turbocharger adjustments for the horsepower rating.

Notes
⚠: Not Verified or Educated Guess
(1) C36-7s were offered with various trucks classified as FB-3; Adirondac and GSC castings with various mountings for brake cylinders or clasp brakes could be found. Otherwise, the difference was cosmetic.
(2) Very late production units used an electronically-blown braking grid, mounted behind the cab. This potentially improved dynamic braking performance, however the main advantage was less wear on the engine.
