What is train tracks dmz?

As an AI language model, I do not have access to current events or news articles that are not within a dataset. However, in general, the term "DMZ" stands for "demilitarized zone," which is a buffer area between two countries or territories with military forces. If there are train tracks running through a DMZ, they may be subject to restrictions or security measures to ensure the safety and security of the area. Some countries with DMZs and train tracks may include North and South Korea, Israel and Palestine, and India and Pakistan.
