Iowa Interstate 150 and sister SD38-2s 154 & 155 lead
a foursome of GP38-2s (711, 706, 710 & 708) en route
to Walford, Iowa, with the daily Iowa City to Cedar
Rapids turn. Heavy trains and stiff grades dictate an
abundance of horsepower on this line, which is owned
by the Cedar Rapids & Iowa City Railway (CRANDIC).
