Can anyone explain why the luas map shows a green line box next to the O’Connell upper stop and a red line box next to the Busáras stop?

A friend from The States asked me and I couldn’t answer!!

The boxes confirm the line the stops are on but I can’t understand why!! They are both beside a stop where you switch from one line to the other but by that logic why is Abbey St or Jervis not marked the same way??

  1. The only thing I can think of is it’s a crappy way to show the two lines for colourblind people (by printing the colour names in a crappy way next to each line), and the GPO stop is an error.

  2. It’s to show the routes (not lines) diverging.

    Busáras -> Connolly

    Busáras -> The Point

    This shows the routes splitting and the line no longer being spined and not having combined frequency.

    As per the one at O’Connell, it shows the services that continue on towards the Broombridge interchange and then the other services that go around the loop via the bypass track at the top of O’Connell Street.

    Take it as a fork in the road

    2 people walk from X to Y via Z
    2 other people walk from X to A via Z
    The two routes they take split after Z
    So if two people take each route, on what we call “the spine” in this case, X to Z would then have a combined frequency of four.

    And the one at Marlborough simply shows the connection to the red line
    On other maps it’s typically shown as

    O’Connell GPO <–> Abbey St <–> Marlborough

    Hope this helps.

  4. They’re calling out services available on each stop. So for the “red oconnel st” you can transfer to the red line from the green line. The “green oconnel st” means only the green line is available there. Because both stops are on oconnel st they needed to make a distinction. “Red Busarus” shows that you can access both luas and bus services from that stop.

  5. O’Connell stop is on the green line. Busáras stop is on the red line. There are connections between those but the distance is so short it’s easily walked.

  6. They’re showing transfers available at those stops.

    So above the label for Busaras it shows a bus icon to explain you can transfer here for national bus services and it has a tram icon with “red” to say you can transfer to the red line service here (possibly meaning it’s the first place that both red lines i.e. Tallaght and Saggart go through)

    In the centre above the label for Abbey Street is an icon saying Green line as Abbey street is where you interchange from Red to Green line.

    O’Connell and Marlborough have red line as here is where you interchange from Green to Red line

    O’Connell Upper has Green line I presume because this is where some Green line services diverge, some will continue right on to Broombridge and some will simply take the short loop to Parnell so O’Connell Upper is the furthest one can go on any tram before having to make sure they have the correct service
