Faced with Union Pacific no longer operating its Union Pacific lines (North, Northwest, and West), Metra is considering renaming its lines. News article. Metra webpage.
The three choices are
(1) keep the present names except for renaming the Union Pacific lines.
(2) number all the lines in a single number scheme (M 1-14), with one map color for all routes.
(3) number the lines in the three cardinal directions (N 1-4, W 1-3, S 1-7) and color-code them on the map for the four Chicago termini.
I really like (3), and filled out the survey accordingly.
