I have the 2015 version of this book and I figured 4 years is a good enough time to get an updated version with all the changes made in recent years. The 2019 Tracks of the New York City Subway will begin shipping in December (of this year) and you can order your copy now. This publication is still the king of all track layouts of the entire NYC transit system (including abandoned stations).
