BN F units ran out of Northtown yard in Fridlay Mpls MN until 1984. Some F7B units worked as hump units at Northtown yard in the later 1980s. A few F units survive on the BNSF today as rotary snow plow power units. In this photo note the Harco spark arrestors on the trailing F7B unit. This is probably an ex Great Northern F7.B |
