1. Introduction 1. Introduction

Nowadays, the impact of the railway sector on the economy, social, and environmental sectors has been debated among governmental institutions. Regardless of the type of rail transportation, both freight and passenger trains point to be beneficial for the world’s future if the sector can compete with the other transportation industry. For the pop ulation, railway transportation is a good choice either for short, medium, or relatively long distance trips if they can provide comfort and good trip experiences. Additionally, since trains permit avoiding tra ffi c jams, the population has preferred the railway vehicle to travel to work. Still, the railway can be competitive with the aeronautical industry, since the waiting time to board can be quite inferior.
