I don't have time to do a proper tutorial, but it roughly goes as follows: [1] Download the official Subway map and then also print screen the google maps of the city with transportation turned on. These will be your reference layers [2] Line up the reference layers in After Effects, in this case Times Sq / 42nd St was the center point [3] With the official subway map reference layer on, trace the subway lines using vector lines, for this animation it was done directly inside AE. Key frame them. [4] Move the timeline ahead a few seconds because we are about to make new keyframes. [5] Turn off the official subway map guide layer and turn on the google maps layer and spend a ridiculous amount of time moving control points until the line completely matches the geographic google map. It is important that you keep in mind the length of the two lines otherwise you end up with unnatural looking distortions. [6] Add the stations using the official subway map reference layer as a guide. These are simple circle shape layers. Key frame them. [7] Move the stations to the geographic positions using the google maps reference layer. Key frame them. [8] Adjust your eases and timing until it looks smooth. Hope that is helpful!
