Many of those "take a train" routes aren't really your destination, though. For example, practically everything involving LAS is connecting to something else which goes further. Orlando is probably the terminus thanks to Disney, but ATL is likely not the originator. Probably the only route which definitely isn't a hub connector is LAX-SFO as both LAX and SFO are already hubs in and unto themselves. Maybe, LGA-ORD also falls into a similar category.
