Train Surfing, Bangladesh

Many railroads take a strict view of people hopping freight trains, and employ railroad police, also known as "bulls", in an attempt to prevent the practice. Among other duties, railroad police are charged with preventing trespassing on railroad property, which includes freighthopping. Railroad police officers typically patrol in utility trucks, SUVs ("bullmobiles"), or even standard police cars.
Decline of freighthopping
In recent decades, the traditional role of hobos as itinerant workers has fallen off. Most itinerant workers in modern times have automobiles and drive between jobs, alternatively they may use public transportation, and live in many types of temporary housing. As seasonal agricultural work became the province of immigrant workers, and other seasonal work became increasingly lucrative, freighthopping became mainly used by the homeless population, thrill-seekers, and people who enjoy traveling across the countryside under the open air.
