You would have to drive to a train station. Waterbury being the closest roughly 10 minutes, but doesn't provide the best service or safe secure parking. I live in Southington and have never bothered leaving from Waterbury. Its also not direct you have to transfer in bridgeport, I believe. the next closest and much more efficient station is in New Haven roughly 30 minutes away. Definitely the closest and most efficient station. If you prefer to drive further to another station, since driving can be much faster, but don't want to drive into the city. I would recommend Stamford or Greenwich roughly an hour from Southington, which are also direct, often express and provide safe parking and good service.

The only Number 6 train you may be referring to is the MTA Subway number 6. This train line does not go to NYC Penn Station, but does go to Grand Central Station. The best suggestion is to take the MTA "S" train (for Shuttle) that gives you a very fast trip from Penn Station to Grand Central. There you will find the number 6 train.
