, Russia. Due to overcrowding inside the train some passengers are forced to ride between the cars The phenomenon of riding on the outside of trains came with the appearance of the first railway lines. On a series of first railways, riding on rooftops and
footboards of trains was common, but over time, starting from the second half of the 19th century, with an increase in the sizes and speed of trains, passenger coaches began to be produced fully covered and insulated from streets with a placement of all passenger seats inside carriages in order to improve the safety of passengers and prevent people falling from a moving train. As trams became more common in Europe and the United States in the early 20th century, overcrowding prompted passengers to begin riding on footboards, doors, couplers and sometimes on the roofs of trams. European conflicts such as the
First World War,
Russian Civil War and
World War II frequently saw soldiers and refugees travelling on the roofs of carriages due to lack of seating. In the mid-20th century, railways in many European and American countries took measures to reduce overcrowding in carriages and prevent riding outside of them, so the prevalence of train surfing in those countries decreased. In some countries of Southeast Asia and Africa with a high population density, however, the problem of overcrowding of different vehicles, including trains, grew rapidly, so train surfing in those countries became a widespread phenomenon. Beginning in the mid-2000s there were frequent cancellations of commuter trains and crowding inside rail carriages in the Moscow region, especially since the late 1990s, as gridlock grips this metropolis of 30 million without a single metro system, and the city comes up with alternative transport such as
car jockeys. Jakarta traffic is the most gridlocked in
Southeast Asia, perhaps among the worst worldwide. It has built a
bus rapid transit system, but with little success, as there is no separation from the heavy traffic. The tropical heat and
urban heat island effect also makes the top the only place on the train with plenty of air circulation. Since 2013 the practice has been eliminated after the state railway company
Kereta Api Indonesia modernized the ticketing system, allowing tickets to be sold up to 90 days in advance, and including check in requirements along with increasing the amount of rolling stock. On
KRL commuter services, stations are modernized by installing
turnstiles, implementing contactless payment and locking down the station. All non-commuter train now have passenger limit of 100 to 110% while previously a service could run at 200% or more capacity. == Travelling without a ticket ==
