NYCTrainSign API

This site is a reverse engineered version of the control panel behind the now defunct NYCTrainSign. It is not run by the original NYCTrainSign company nor does it have anything to do with the original NYCTrainSign company.

Follow the instructions below to connect your sign to the API. Once you have a claim code, use the button below to claim your sign and get the control panel link.

For more details about how I got sign and how everything works read my blog post.

Open Source

The code behind the API as well as the exploit are open source.

If you are curious about the code that powered the original NYCTrainSign I have also published it.
