Rail Logistics plans to expand its fleet of refrigerated containers on the Cold Train and is adding several delivery destinations in the Southeast and New England beginning in August.

Customer requests prompted the Overland Park, Kan.-based Rail Logistics to run tests in the first half of this year to find out if expanding service was feasible, according to a news release.

Cold Train successfully transported about 100 test loads from Washington state to Florida, Georgia, Pennsylvania and other destinations in New England, said Rail Logistics Cold Train president Steve Lawson in the release.

The company plans to add those destinations to its regular service beginning in August, the release said.

To handle demand, the Cold Train’s fleet of 53-foot Hyundai refrigerated containers was recently expanded to 300.

Shipments of fresh produce have grown since Rail Logistics launched the Cold Train in 2010, the release stated. That year the train was delivering about 100 containers a month. In 2011 that increased to 300 per month. So far in 2012, the Cold Train has been hauling about 400 containers a month, with projections that will increase to 600 per month by the end of the year.
