Not your typical sight nowadays. However, CP 421 has proven a few times this sight still is possible. Six variants of SD40-2's (5988, 5953, 5959, 6072, 6040, 9006) are for power of this northbound today. After doing work at Utopia, it pulled into the siding at Essa to wait for its counterpart, 420. Thanks to those who gave the heads up for this stellar lashup on CP 421.
