Charlotte's mayor is expressing renewed optimism that CATS' Red Line commuter rail line will come to fruition. 

The line, which has been discussed for more than 20 years, would stretch from Uptown to Mooresville.  

"Here we are decades later talking about this, so I am enthusiastic about the concept that we can make this happen this time," Vi Lyles, Mayor Charlotte, said on WCNC's Flashpoint.
