&gt; Even today, it’s not hard to reach the tracks if you want to; plenty of holes and gaps remain. A sergeant with the Philadelphia Police Department told me that the rail bed is popular with addicts and dealers. “And let me tell you,” he said, “you couldn’t build a fence high enough to keep them all out.”<p>As with software piracy, the solution is not to make the tracks unreachable - that&#x27;s impossible. Instead, make them less desirable than the alternative.<p>For people trespassing to walk on the tracks to get somewhere, add good sidewalks or park paths. For people crossing between one building and another, add official pedestrian crossings and signals, or build bridges and tunnels that are nicer to walk than trying to hop even a 4&#x27;, no-barbed-wire fence.<p>For addicts and dealers, make non-dangerous drugs legal. I am not sure what to do about dangerous drugs and other crime that needs a secret place to meet, but I think access would make this much easier.<p>People walk a rail near me because it&#x27;s literally the safest way to get from the town (restaurants, the park, ice cream, shops, the river a little off-screen to the southeast) to the high school and the Stoney Creek neighborhood to the North:<p><a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;0pBaSa4.jpg" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;0pBaSa4.jpg</a><p>Division is not walkable. Lamareaux is mostly, but the sidewalk crosses back and forth, traffic is fast, and the railroad is much more direct.
