Not on my usual Lynx ride, but I have passed this station many-a-time while walking the Rail Trail and now that there are apartments popping up all over the place in SouthEnd, this is becoming a pretty popular stop.
The Carson Lynx Station is the "last" stop on the line before the lynx crosses over I-277 and into Uptown. It is also good to note that the trail still continues on under Moorehead, but then diverts you over to Moorehead/College St if you are trying to walk in. No pedestrian traffic allowed on the light rail bridge over 277.
A lot of folks get on the train at the other end of the line in Pineville, so by the time the train reaches Carson, it's pretty packed (depending on the time of day... I'm talking rush hour when it is pretty packed). No men employed to squeeze people in the trains yet (like Japan), but if you value your personal space, I would either try to get an earlier train, or just avoid the rush hour altogether.
Other than that... pretty standard light rail station. No park and ride here.... but lots of residential places nearby and you've got TWC News 14 building behind the station off of South Blvd and the Midnight Diner about a block away.
