Sichuan is a populous province in China, but also the western economic leader, comprehensive strength in the country is also at the forefront of the position. However, due to the complex terrain and large population, the railway construction has always been in short supply. Up to now, there are still many large counties with a population of one million that do not have access to railways. Even compared with neighboring guizhou, there is a big gap.

At present, the biggest vacuum zone of sichuan railway is in the middle of sichuan, such as an yue, fire hong, three economically developed large counties with a population of one million, there is no railway up to now. Also let north sichuan to south sichuan and other places of railway traffic is very inconvenient, there is no direct railway, all need to chengdu bypass, time-consuming and laborious.

Therefore, many years ago, sichuan put forward the mian sui intercity railway planning and ideas. As early as 2011, the state council included the railway in its reply to the plan for the chengdu-chongqing economic zone. The line starts from anzhou station of chenglan railway, passes through mianyang city district, santai county, suining shehong county, chuanshan district, anju district, ziyang city anyue county to neijiang city. The line is nearly 300 kilometers long, with a total investment of 41.7 billion yuan.

The basis of the current of the inter-city railway has been in the building, so the railway was completed, in neijiang can be connected to the sichuan inter-city railway, arrived in zigong, luzhou, yibin city, access into your railway, eventually become a south central sichuan and the high speed channel, is beneficial to the tens of millions of people, is currently one of the most important in sichuan inter-city railway.

However, awkwardly, because the railway is connected to sichuan prefecture-level cities and ordinary counties, to rely on these cities to jointly build a railway, capital pressure is still very big, so the railway investment has been not smooth, many times to the public bidding failed. And the good news is, last year mian sui inside railway limited liability company was formally launched, meaning that the start of another step.

In addition, with the advent of the high-speed rail era, the intercity railway, which was originally planned to run at 250 kilometers per hour, is also facing questions about whether to upgrade to high-speed rail. Since last year, many netizens have called on forums and government platforms to upgrade the inter-city railway in miansui to a high-speed railway with a speed of 350 kilometers per hour, so as to achieve the goal in one step and avoid the fate of repeated construction.

Reply to this, the relevant departments also said that at present the railway is still at the beginning of the line site selection and planning stage, the integrated along the city's economic situation and the actual capacity to comprehensive consideration, after all, the railway passing through areas are not rich ordinary city, its status cannot be compared with the national backbone network, if after repair, traffic can't guarantee, will face the problem of huge losses for a long time.
