As of January 8th, 2020, the list for this particular exam has been published. To view your list number, click here and type either your name or '8600' in the search box on the top right, followed by pressing 'enter.'
While we are waiting to get called, this downloadable PDF file might be of interest, especially to those who have a low list number. In addition, for those of you who are seeking more information, I would encourage you to read the Track Worker 3600 Hiring Process thread. This thread contains a lot of useful information.
Good luck and stay safe out there!!
