Sonia Nazario 's best-selling novel, "Enrique's Journey", also depicts the process and obstacles of train migration. While this book mainly focuses on the journey of one person, it speaks for the thousands of other migrants who have struggled to reunite with loved ones. Nazario describes the emotion and difficulty experienced by entire families who are separated by the necessity to become more economically stable. The dangers of crossing Central America and Mexico by train are described in explicit detail as migrants of all ages face street gangs, corrupt officials, hunger, exhaustion, discrimination, poor weather, and deadly trains.
Sometimes extreme congestion of commuter trains becomes a problem. For example, an estimated million passengers ride every day on Yamanote Line in Tokyo , Japan, with its 29 stations. For comparison, the New York City Subway carries million passengers per day on 25 services serving 472 stations. To cope with large traffic, special cars in which the bench seats fold up to provide standing room only during the morning rush hour (until 10 .) are operated in Tokyo ( E231 series train). In the past this train has included 2 cars with six doors on each side to shorten the time for passengers to get on and off at station.
