While most of the crossings don't specifically prohibit access, out of respect for our neighbors I would discourage racing up and down these roads to see our trains go through. Kids play on many of them, the property owners, including the fire chief at one, already must navigate these narrow, winding dirt roads, and then pay to maintain them, etc. In short, our neighbors are friendly and tolerate our volunteer's traffic to maintain the line- we don't want to overstay our welcome by overusing their roads.
Limited, respectful use of some of these roads has been and probably could continue for photography. Alternatively, the train will drop you at a y location for later pick up, and you can walk the right of way between locations.
See ya
