Public Railways Transportation between Turkey and Balkans
toc

Since being mostly cheap, safe, comfortable and adventurous, railway journey is still one of the most popular travel options in Europe.
 * The public railway transportation system in Turkey is wholly operated by Turkish State Railways (TCDD). Turkish State Railways operates its various trains mainly within domestic lines. However, there are some scheduled travel tariffs from Istanbul to many Middle East, Balkan and further European countries. The idea in this case study is to assist the passengers in choosing the right, cheap and most convinient way to travel from Istanbul to Balkan countries by making use of Prologa Software . **

Turkish State Railways offers various railway connections to Balkan States. For instance, Bosphorus Express oscillates between Istanbul and Bucharest. Transportation between Istanbul-Sofia and Istanbul- Belgrade are provided with the wagons hitched onto the Bosphorus Express train. Besides Bosphorus Express, Filia Express (Istanbul Dostluk Expresi) oscillates between Istanbul-Seloniki and stops by various cities in Greece. Transportation to further European countries are generally operated by InterRail and Turkish State Railways collaboration but our case study does not scrutinize this cooperation.

**Conditions, Rules and Actions**
Decision tables are a precise yet compact way to model complicated logic. Decision tables, like [|if-then-else] and [|switch-case] statements, associate conditions with actions to perform. But, unlike the control structures found in traditional programming languages, decision tables can associate many independent conditions with several actions in an elegant way.(1) In this case study rules, conditions and actions are detected in accordance with a passanger's intended destination, prefered traveling class, willing to have sleeping cars. These preferences of the passangers are taken into account in order to create the suitable and efficien Decision Table. **
