GREENWICH, Conn. (AP) â¿¿ Railroad operator Genesee & Wyoming Inc. said Friday its October traffic increased 14.2 percent as it expanded its rail network and boosted shipments of metals and minerals. The Greenwich, Conn., short-line rail company said it hauled 84,331 carloads in October, up from 73,867 in the same month last year. Excluding traffic from a pair of railways that were acquired in the past year, the company said carloads increased by 2.4 percent due to an increase in salt shipments from the New York/Pennsylvania region and metals shipments in the South. Overall, shipments increased the most for metals (29 percent), minerals (16 percent) and farm and food products (12 percent). They dropped for vehicles and auto parts (16 percent) and coal and coke (9 percent).
