Train services are usually scheduled and use a small number of stops for loading and unloading. In Western Europe, intermodal freight is a rapidly growing market, unlike block trains and single-wagon services. Kazakhstan alone has about 30 container terminals, all handling a small number of containers. About ten terminals are in the Almaty area alone, the biggest handling a volume of about 30 000 twenty-foot equivalent units (TEUs) per year, or about a train a day.
