visual changes to subway map

With the current subway map its not apparent where we are on the map. Suggestions to improve the visual effect include making the horizontal line thinner and/or the 'gray' location indicator to something more obvious like red or blue.

Now that I'm thinking about it, red or blue may clash with users color scheme. Unless the ability to change it is exposed to the user.

That said, the previous/next buttons are set as green. So... maybe green like them?
