In terms of the airfreight service, the analysis assumed that 747 jets would be used for cargo
flight operations with a mix of large and smaller loads. In order to accommodate the projected
volume of cargo, approximately 32 flights (16 arrivals and departures), are required. The rail
operation was assumed to reflect the air operation, with the first trains arriving at Rochester from
Twin Cities at least one hour before inbound aircrafts arrive. Since air movements are typically
between 7 p.m. and 10 p.m. inbound and 2 a.m. and 5 a.m. outbound, trains would arrive
between 6 p.m. and 10 p.m. and depart between 1 a.m. and 5 a.m.
