Notes
⚠: Not Verified or Educated Guess
(1) An aftermarket modification was made available that allowed for electronic blowers to the dynamic braking system, the most famous of these being the C36-7i Estonian rebuilds. Dynamic braking capacity remained unchanged. It is unconfirmed any B series Dash 7s were modified with this.
(2) Supposedly very late models would share the same alternator with the C36-7/B36-7, which features generator transition. However I've been unable to find anything to substantiate this.
(3) Weight comes from a batch of SP B36-7s; unsure if this would carry over with the B30-7
