Reportedly, by the end of 2012, the journey from Wuhan to Beijing will only take four hours by high speed rail. For this amazing journey, Wuhan Steel (Wisco) has made lots of efforts for it.
It brings more profit for steel mills if they produce high end heavy rail. 
In this case that Wisco produced 170,000 tons of heavy rails for the main construction in the first nine months this year.
Also, in March this year, the company exported 12,000 tons of heavy rail to West Africa.
