In 2013, as the Chinese government launched a series of investment projects aimed at boosting domestic demand, the economy showed signs of stabilization and recovery. This led to an increase in coal demand. According to the evolving supply and demand dynamics in the coal market, the Ministry of Railways announced initial targets for the Daqin Line, setting the annual transport volume at 450 million tons—an increase of 24.11 million tons compared to the previous year. The Taiyuan Railway Bureau was assigned 350 million tons, the Huhhot Railway Bureau 91.5 million tons, and the Lanzhou Railway Bureau 8.5 million tons. At the port level, 386 million tons were allocated, accounting for 85.7% of the total traffic. Qinhuangdao Port planned for 224 million tons, up by 5.86 million tons from the prior year. SDIC Jingtang (Donggang) arranged 53 million tons, an increase of 6.36 million tons, while Caofeidian Port set a target of 70 million tons, up by 14.78 million tons. However, Jingtang Port saw a reduction of 840,000 tons compared to the previous year.
Despite these increases, challenges remained. The large-scale transportation channel for Shanxi Jinmei still faced bottlenecks, and the Daqin Line was nearing saturation. The Taiyuan Railway Bureau had initially set a transport capacity target of 450 million tons on the Daqin Line, which was currently under review. Meanwhile, the new line through the Yellow River was expected to add 30 million tons of transport capacity. Electrification of existing lines such as Keihin, Shita, and Waiting was nearly complete. Additionally, the Jinzhongnan Railway, Shanxi’s second-largest coal transport route, had a capacity of 200 million tons and was scheduled to start operations in 2014. Most of the 2013 capacity growth was concentrated in central and southern Shanxi, but the limited expansion of Bohai Sea ports reflected the constraints of railway capacity.
The coal transportation bottleneck in Inner Mongolia began to ease with the completion of the Shenzhou Yellow Line expansion. This year, the newly added capacity reached 150 million tons, mainly serving Shendong Group, Zhungeer, and Jinjie resources, with most flowing to Huanghua and Tianjin Ports. Both the Tianjin Shenhua Coal Terminal and the third phase of Huanghua Port received significant infrastructure support.
The Daqin Line primarily served Qinhuangdao and Tangshan Ports. Qinhuangdao included Qindong, Qinnan, and Liunan, while Tangshan included Jingtang, SDIC Jingtang, and SDIC Caofeidian. The first phase of Caofeidian Port, commissioned in September of the previous year, started contributing this year, and the second phase was completed in July. As resource integration advanced and production in Inner Mongolia increased, the national coal supply grew steadily. Most Mongolian coal flowed into Tangshan Port, though the consolidation of Qinhuangdao Port and the renewal of Phase IV dumper systems caused some disruptions in coal throughput. However, Tangshan's capacity expanded rapidly, with two new terminals coming online or planned. Due to delays in the construction of the new Jigang Railway (Mengjing Line), coal from the Daqin Line would be mainly directed to Tangshan, with some diversion to Qinhuangdao, especially if Inner Mongolia’s resources were redirected.
The Shuohuang Railway, operated by Shenhua Group, serves as the "North Coal South" middle corridor, offering guaranteed resources and capacity. Its main ports are Shenhua Huanghua and Tianjin. Last year, around 130 million tons of high-quality Shenhua coal were shipped through these two ports. The Shuohuang Railway is currently expanding, and upon completion, it will significantly boost its capacity—expected to increase by 30 million tons this year. The current capacity stands at 250 million tons, and by the end of 2013, it is projected to reach 300 million tons.
Lastly, the Mengxi-Huazhong Railway, stretching 1,860 kilometers from Ordos in Inner Mongolia to Ji'an in Jiangxi, is set to begin operations in 2017. It will have a long-term capacity of 200 million tons and is now entering the final stages of construction.
