In time, the ekiben became popular at train stations all over the country, and some stations became famous for their specific ekiben. The sellers were coming on the platforms and the travelers were paying and receiving the meals directly through the train's open windows. Later, after the appearance of air conditioning and the high-speed trains with fixed windows, the meals had to be sold only at on platform stalls, and the popularity of ekiben started to decrease.
Today, in some places, such as Tokyo Station, you may still be able to taste it. Photographed here is a delicious ekiben from the Saitama Railway Museum.
