In 2017 PTV launched their new network map, which contained all their heavy rail services on the one map for the first time. The previous map hadn't shown V/Line services - it only showed Metro services, and it prioritised showing which ticketing Zone each station was in. Since Zone 2 has (sort of) been eliminated now, this was less important to show - so instead they've colour-coded it to show the different groupings of lines. This same colour-coding is now being applied to information screens at stations, and so on - which is definitely a good thing.
