My local transit authority has 5 trolley lines which travel from West Philly into Center City via a tunnel. It has one additional trolley line which runs in the city. There are also 2 trolley lines which only run in the burbs.
The first 5 trolley lines are represented on the main rail map, but only barely. The other urban trolley line, which only recently had service reinstated, isn't represented at all on either that map or the specific trolley map. And the 2 suburban trolley lines each have their own color.
I'm hoping the newly green schedules for the suburban trolleys reflect a move towards better integration/representation of the trolleys on SEPTA maps.
It's the little things.
