The weekly average intermodal rail volume for January rose to the highest level on record for the month, the Association of American Railroads reported.
Intermodal volume reached a weekly average of 236,657 units in January, and total intermodal traffic rose 1.3% to 1.2 million for the month, AAR said in its weekly report.
Railroad carloads excluding intermodal increased 0.4% year-over-year to 1.3 million units, according to the AAR report.
Seven of 20 commodity groups showed increases, led by grain (13.2%) and petroleum products (10.4%).
"Railroads are very good at operating their 140,000-mile long, outdoor 'factory floor' in all kinds of difficult weather. That said, in many parts of the country, January took the term difficult weather to new lows, as in low temperatures, for recent years," AAR Senior Vice President John Gray said in a statement.
