* Code for GP50 and AlCo/RS units undetermined.

*There was also that one Plymouth unit that was forever leased out, the 2401. It had code 20.

* It's not certain if the #4666-4669 (which were actually the test beds for the B30 series units) had the same codes as the B23's or if they were issued separate codes.
