Hello Everyone---CP has chosen to use AC powered locomotives compared to CN's DC diesels---to be honest I can't tell one from the other.Can anyone point out any distinguishing features on these two types of locomotives

Here's CP---AC44CW 8521 and ES44AC 8780





Canadian National's ES44DC 2226 and C44-9W 2633
