A simple visible DTA logo is all that is needed.
Instead of waisting cash re-painting, there should be the re-naming of the different lines.
For example, Luas we have the Red and Green line. Later we'll have (probably) the yellow (lucan), purple (Liffey Jtn, hopefully Finglas) (pick whatever colour you want), the metro has north, west, (maybe south later) and the Dart, A and B (maybe).
A simple colour/number code system is needed like you see in Madrid.
