NS 229 is probably the hottest train running south down the CNO&TP and on to Florida. It's usually a shorter train--3000'-4000' on average. The majority of the train is UPS business and runs non-stop (besides crew changes) between Cincinnati and Jacksonville. Another interesting tidbit about this train is that it's had the same ID and routing ever since the 1970's.
