DPW(who I work for) would be responsible for the maintenance of pretty much everything in Schenley Park including this trail. The Park Foreman for Schenley Park has tried everything within reason to close the trail to be used for official vehicle use only including constructing new gates as well as installing locks and providing keys to the appropriate personnel including emergency personnel(police and fire/EMS). Again, there is good reason for DPW trucks to be on the trail given that they must check each garbage can along the trail as well as perform a variety of other tasks in that area(the same applies to the EFT). Unfortunately, people have taken it upon themselves to destroy public property in order to access that trail by vehicle which is unbelievably frustrating. I can’t speak to the police policy for patrolling trails though I don’t know how the lighting issue would affect their policy during the day which seems to be when @stefb witnessed them. I would gladly attempt to reach out to the police but that’s also a concern, along with regular vehicles using the trail, that should be voiced directly to Zone 4: 412-422-6520. Additionally, I’m not personally familiar with plans regarding lighting on the JHT but I’ll ask around.
