Hi Cameron. I live in Chicago and our commuter rail Metra is considering rebranding its lines and recently released two proposals. I thought you and your readers might enjoy reviewing them. The announcement, proposed designs, and link to a survey are here. The proposed designs are available in a PDF here [I’ve also reproduced these below – Cam].
I’ve been riding Metra for more than 20 years and I’ll be the first to acknowledge that the current line names have their faults but the proposed designs are “interesting” to say the least.



Transit Maps says:
The obtuse naming conventions of Metra’s commuter lines are like the names of lines on the London Underground – they have a certain old world charm about them, but they’re absolutely terrible for anyone but the most seasoned of commuters. Hey, let’s have some lines with “Milwaukee” in their name that don’t actually go there! To be honest, I thought that these line names would never be changed in a million years, so I’m kind of ecstatic that this discussion is even happening.
I do think it’s important that these rough little diagrams are almost certainly just tools to illustrate the status quo and the two new concepts, so I don’t think we need to get too hung up on the design right now – once the surveys have been done and some data compiled, then more complete (and better) maps will be generated.
That said, I think the concepts do have some problems.
The “cardinal direction” concept perhaps gets in its own way by having both directional prefixes and colour-coding by downtown terminus. This leads to all of the directions being denoted by multiple colours (two for north, two for west – both of which are the same two colours, yellow and green – and three for south). Maybe there could be two separate colours for the two “halves” of Union Station to prevent that station’s yellow routes from spreading out and dominating the map? The order the lines are named in also seems haphazard – the bullets for the northern lines count down when read from left to right, which goes against our natural reading order, while the southern lines don’t seem to have any natural order to their numbers – c’mon, the Millennium Station lines are just crying out to be S5, S6 and S7 at their outer termini from left to right, instead of S6, S5 and S7!
This problem carries across to the “M Numbers” diagram – there’s no discernable pattern to the numbering of the lines. A hub-and-spoke network like this should really be numbered in sequential order from the outer end of each line. Normally, this would start at the twelve o’clock position and go clockwise (we’re familiar with how a clock works, so this is can be a very intuitive design shorthand), but Lake Michigan forms a natural barrier to this system – you’d start at “M1” then have to jump halfway around the diagram to get to “M2”! Perhaps starting with “M1” to the west of the map would work better in this instance?
Our final word: These are very early concept diagrams with a lot of work still to done, but making things as easy as possible for commuters to understand has to be the end goal, and I’m not sure either of these are quite doing that right now. Still, it’s going to be interesting to see where this goes! If you use Metra, I definitely encourage you to go and do the survey.
