Turkish State Railways (TCDD) indicated that the number of railway accidents since 2000 to 2017 decreased.
TEHRAN UIC RAME: According to statistics, the number of train collisions in Turkey decreased from 40-45 in 2000 to between zero and five in 2017, with the development mainly indebted to a higher degree of signalization nationwide. Turkey's network is preponderantly made of single tracks and, in spite of popular belief that collisions occur on single-track lines, most of them in fact have been proven to occur on multiple ones. Most of accidents in Turkey have been mainly caused by derails, which, in turn, are caused by infrastructure, speed, or wheel issues. The Pamukova and Corlu accidents are examples in this sense, with the Pamukova one being caused by trains in questions having been found to travel at speeds over the maximum limit, whereas the Corlu one was caused by derailments. On the whole, train accidents caused by derails went down from between 80 and 100 in 2000 to 0-20 in 2017. As for level crossings, collisions occur mainly where a barrier isn't set in place, with these going down from more than 350 in 2000 to between 0 and 50 in 2017. Present legislation requires that new railway lines be equipped with barriers when being built. The number of individuals being hit by trains, on the other hand, decreased from between 150 and 200 in 2000 to 0-50 in 2017, whereas the number of those falling out from trains fell from 60-70 in 2000 to 0-50 in 2017.
