Will cut the use of coal and carbon emissions

Biomass refinery developer Inbicon is taking baby steps in reducing carbon emissions by utilizing coal steam for cellulosic ethanol. China Energy Conservation and Environmental Group (CECEP), on the other hand, is pummeling coal consumption and carbon emissions with the largest stand-alone building integrated photovoltaic (BIPV) project, which started transmitting power to the to the electric grid on Sunday in Shanghai. 

The new 6.68 megawatt solar station, which cost $23.6 million to build and has the ability to power 12,000 Shanghai homes with 6.3 million kilowatt-hours (kwh) of electricity per year, was built over the recently completed Hongqiao Station, which lies over the Beijing-Shanghai High-Speed Railway line. According to the latest reports, this new solar system can decrease coal consumption by 2,254 tons and also cut carbon emissions by 6,600 tons. 

"The project is another manifestation of China's commitment to reducing carbon emissions to fight climate change," said Yu Hailong, general manager of the project's developer, CECEP. "It comes after the country set a voluntary target of cutting carbon intensity per unit of GDP by 40 to 45 percent by 2020."

This solar station is covered with 20,000 solar panels over the 61,000 sq m roof and has produced 300,000 kwh of power since the operation started two weeks ago. It is meant to spread solar energy awareness as well as the development of environmentally-friendly railways throughout China.

"BIPV technology does not take up extra space, because it is integrated into buildings' design and construction," said Zheng Jian, chief engineer of the Ministry of Railway. "It is especially suitable for China's eastern areas, where there are limited land resources yet greater energy demand."

The solar station built over the high-speed railway in Shanghai is the largest in the world, but not the only project like it in China. The Wuhan Station, a part of the Wuhan-Guangzhou High-Speed Railway, received a similar integrated photovoltaic solar-powered system that was connected to the grid back in May of this year. The difference is that this solar station is about three times smaller than Shanghai's. But this goes to show that China is achieving their goal of spreading the idea of solar-powered stations and implementing them in certain areas to reduce carbon emissions and use of coal.

since we're already talking about trains

Since the government already owns the land that the railroad tracks are laid on along with a buffer zone to both sides of the tracks, why not line the whole railway with solar panels then you don't need to take up a huge plot of land to put a bunch of solar panels on in a single concentrated area like some of the projects (not this one) that we've heard about

The whole point of an elevated railway is that it doesn't need a buffer zone.

Producing energy in a single location is also more efficient than doing that along >1000km railway line.

Actually there are benefits to spreading out distribution. To minimize power loss due to transmission you want to use the power as close to the generator as possible. A city will obviously suck up every watt that this thing generates though, so it doesn't matter either way.
