According to Jim Scribbins' book, "Milwaukee Road Remembered," there doesn't seem to have been a definitive point in which the Copper Country Limited joined the timetable. Its first appearance was during March of 1907 listed as trains #2 (southbound) and #3 (northbound). The route it plied required a little more than 12 hours departing Chicago late in the evening, running through Green Bay, and arriving at Calumet, Michigan the following morning. Interchange with the DSS&A was carried out at Champion, Michigan, (a Milwaukee-Marquette sleeper was interchanged 10 miles south at Republic, Michigan) which operated the train to its northward destination near the shores of Lake Superior. During its early years the Copper Country provided a consist including coaches, sleepers running through between Milwaukee and Marquette (Michigan) as well as Chicago and Calumet.
At this time it seems the then-Chicago, Milwaukee & St. Paul considered the train as one of its more notable runs but as the years passed its status apparently faded especially with the arrival of the Hiawathas. During the latter half of 1930 a number of changes came to the Copper Country including a new train number (#3 became #9 with the former having been renamed as the Iron Country Limited, a short-lived train that survived only a few years) and a makeover of the consist which now offered coaches, a diner (Chicago-Green Bay and Channing-Calumet), a parlor (Chicago-Green Bay), and a pair of sleepers then operated by the railroads themselves (Chicago-Calumet and through between Sault Ste. Marie via Pembine, Wisconsin operated in conjunction with the Soo Line).
As Mr. Scribbins notes in his book the depression years were hard on railroads and the southbound Copper Country stopped running through to Chicago with the Pioneer Limited picking up its cars in Milwaukee. This operation continued on and off through the diesel era. The Milwaukee Road was quick to adopt this form of motive power, purchasing its first diesels for passenger assignments when it acquired a pair of E6As from Electro-Motive (#15A-15B) and Alco DL-109s (#14A-14B) in 1941. However, World War II temporarily halted the purchase of more, a process which continued in 1946 after the conflict was over. With the arrival of the Chippewa-Hiawatha on the Milwaukee Division during May of 1938 the Copper Country Limited took a further back seat on this corridor. The new train ran a very fast schedule, provided top-level accommodations, and was completely streamlined, which included its pair of shrouded Class F-3a 4-6-2s.
For many years Pacifics had been primary power for the Copper Country
albeit non-streamlined. As diesels began arriving in ever larger
numbers after the war steam had been entirely replaced across the
railroad by the mid-1950s. Intercity services like the Hiawathas,
and other trains through the Midwest, were led by Electro-Motive models such
as E7As, E9As/Bs, and FP7s (acquired through 1961) while the company
also used Fairbanks Morse Erie-Builts (bumped from more prestigious
assignments leading the Olympian Hiawatha) and a few Alco RSC2s equipped with steam generators for passenger service. The Copper Country Limited
was diesel powered in 1952 and it was quite common to see FP7s, E7As, or E9s leading
the train. When the Milwaukee took over assignments carrying Union
Pacific's City fleet into Chicago starting on October 30, 1955 a major shakeup in train numbers occurred.
The Copper Country's southbound #2 was changed to #10 in correspondance with #9; by then its consist was only a few sleepers and coaches. During 1958 the through Sault Ste. Marie sleeper was discontinued entirely after several cutbacks leaving only the sleeper to Calumet (operated by Pullman) as the remaining such service available (a 6-roomette/8-duplex roomette/4-double bedroom car). As ridership continued to slide the Milwaukee offered the sleeper only three days a week beginning in the spring of 1964 and remained on this scheduled until the Copper Country was discontinued a few years later. While the railroad is fondly remembered for sustaining its regional Hiawathas with first-class services until the end its secondary trains were not provided such luxuries.

For instance, during its final years the Copper Country offered little more than a few cars and its existence persisted almost entirely due to the lucrative U.S. mail contracts that kept many similar trains running all across the country that would have otherwise been retired years before. The hammer fell for most, including the Copper Country, when these contracts were canceled during 1967 (it officially lost its Railway Post Office car in October of that year). With little other reason to keep it and few riders remaining the train made its last runs on March 7, 1968. Interestingly, the Copper Country survived nearly a decade longer than the once-heralded Chippewa-Hiawatha which had been discontinued on February 6, 1960.
