Trains and railroads

I was screwing around, & I thought, why is it that (vehicles that randomly explode) on trains in just cause 3 randomly just do that. the answer came with a crash bomb race, where I noticed a train that derailed without me doing anything. I recorded my findings. PS, I got distracted when I realized 2 trains spawned way closer than normal.<figure class="article-thumb tright show-info-icon" style="width: 335px"><span class="thumbnail-play-icon-container"><svg class="thumbnail-play-icon" viewbox="0 0 180 180" width="100%" height="100%"><g fill="none" fill-rule="evenodd"><g opacity=".9" transform="rotate(90 75 90)"><g fill="#000" filter="url(#a)"><rect id="b" width="150" height="150" rx="75"></rect></g><g fill="#FFF"><rect id="b" width="150" height="150" rx="75"></rect></g></g><path fill="#00D6D6" fill-rule="nonzero" d="M80.87 58.006l34.32 25.523c3.052 2.27 3.722 6.633 1.496 9.746a6.91 6.91 0 0 1-1.497 1.527l-34.32 25.523c-3.053 2.27-7.33 1.586-9.558-1.527A7.07 7.07 0 0 1 70 114.69V63.643c0-3.854 3.063-6.977 6.84-6.977 1.45 0 2.86.47 4.03 1.34z"></path></g></svg></span> <figcaption> <p class="title">Unexplainable derailment in just cause 3-1</p> </figcaption></figure>
