IARR 3802 & 3004 lead a string of ethanol empties southbound past 130th St, just south of Ackley, IA. This is the Iowa River Railroad, and it is by far one of the jankiest operations I've ever photographed. The sheer lean on many spots along this former M&StL trackage would be concerning if they weren't always going 10 mph or lower--but still, crazy stuff.
