An animated GIF composed from the New York MTA hurricane recovery maps from the first to the fourth of November, most obviously showing the restoration of service in Lower Manhattan and across the East River to Brooklyn. Full size version (1.3MB).
The map format changed on the third to not include the parks or some other details, but I neither have the software nor skill to remove them from the first two PDFs. If you do and want to do better, please go ahead.
Source PDFs: Nov 1, Nov 2, Nov 3, Nov 4 (midday); Nov 4 (evening).
