In 1984 IPSCO purchased their first EMD switchers, former BN 456 & 493, NW2s of GN heritage.
Interestingly their arrival did not spell the end of ALCOs, on the contrary two former CP S-3s were purchased in 1991. Both are no longer in service however, while BN 493 turned IPSCO #5 is still at it, complete with modern safety stripes and beacons! Note the rusty part donor nearby, still in full Burlington Northern paint, hes of 1939 heritage.
