Cambodia started operational and providing its Southern Railway Line transport service from Phnom Penh to Sihanoukville Port in 2012. In order to streamline transport efficiency as well as to improve the railroad transport network, Sihanoukville Autonomous Port has cooperated with Royal Railway (Cambodia) Co., Ltd to establish the railroad system and rail container terminal within the port's premises so that the customers or cargo owners can transport general cargo and containerized cargo from Sihanoukville Port to Phnom Penh and vice versa. In fact, the volume of containers transported by rail increased rapidly more than 17,000 TEUs in 2014 and last year the volume increased more than 29,000 TEUs. In the first two months of this 2016, the volume of container throughput increased 40% compared to the same period of last year.
