"The Atlantic Limited" saw the first major change to its route around 1970 when the Saint John Union Station was demolished and CPR's Mill Street yard redeveloped to accommodate the Saint John Throughway and associated urban redevelopment. A new passenger station was built on the city's west side in the former city of Lancaster where new rail yards were developed. During the 1970s, CPR operated the service at minimal levels with usually a single 1800-class E8 locomotive (one of only three, later two, operated in Canada, both by CPR) and a baggage, coach, diner, and sleeper car. Some of the stainless steel Budd Company cars originally ordered for "The Canadian" also made their way onto this train and there was infrequent availability of a dome car as well.
