EMD only built 15 locomotives; the growing unpopularity{{vague|date=December 2018}} of the 6-axle design for passenger service led to the adoption of the 4-axle EMD F40PH as the standard passenger locomotive in the United States. The MPI MP36PH-3S replaced the F40C in regular service in 2003–2004. As of January 2017, no F40Cs are operating. Locomotives #600-#609 and #613 were sent to East Saint Louis, Illinois in 2004 and had their road numbers unregistered with the Federal Railroad Administration. They were all scrapped before 2007. #610 was unregistered in 2004 and was sent to National Railway Equipment in Dixmoor, Illinois. The only F40Cs that remain in operable condition are #611 and #614. Both locomotives are on long-term hold and are stored in Metra's Western Avenue rail yard. DesignThe F40C is derived from the EMD SDP40F; besides the shorter length, the primary difference between the two is the substitution of a {{convert|500|kW|adj=on}} HEP generator for the SDP40F's twin steam generators. It is powered by a 16 cylinder EMD 645E3B, producing {{convert|3200|hp|sigfig=3|lk=in}}. It uses the same frame as the EMD SD40-2, giving it an overall length of {{convert|68|ft|10|in}}.[1] HistoryIn the early 1970s the Chicago, Milwaukee, St. Paul and Pacific Railroad ("Milwaukee Road") operated two commuter rail lines in Chicago: the Milwaukee District / North Line to Fox Lake via the CP C&M Subdivision, and the Milwaukee District / West Line to Elgin via the CP's Elgin Subdivision. The operation of these lines was subsidized by local transit agencies. In 1974 two local agencies, the North West Suburban Mass Transit District and the North Suburban Mass Transit District, funded the acquisition of 15 F40Cs for use on the Milwaukee lines. The locomotives passed to Metra on the latter's creation in the 1980s but continued to operate on the ex-Milwaukee lines.[2] The F40C was withdrawn from regular service with the arrival of new MPI MP36PH-3S locomotives in 2003–2004.[3] Thirteen locomotives were sold to locomotive leasing corporations, although units 611 and 614 were retained and kept on the property in the Western Avenue railyard. In the spring of 2009, units 611 and 614 were placed back into revenue service on both of Metra's ex-Milwaukee Road commuter lines. This was done to cover schedules while the oldest units in Metra's EMD F40PH fleet were being rebuilt. Towards the end of 2016, with many F40PH-2 and F40PHM-2 locomotives being sent out for rebuild, there is an increased likelihood that the 611 and the 614 will be put back into service. Along with a small fleet of HEP-equipped EMD SD70MAC locomotives operating on the Alaska Railroad, the F40Cs were the last six-axle passenger locomotives in daily service in North America. #611 and #614 are retained for the purpose of filling the roles of locomotives that have broken down or are being rebuilt. Despite this, neither locomotive has seen regular service since 2012. {{citation needed|date=August 2016}} Metra at one time did have plans to rebuild F40Cs 611 and 614 to test new prime movers and control packages. Due to a lack of bidders, this plan has been put on hold indefinitely.[4] Notes1. ^{{Harvnb|McDonnell|2002|pp=142; 144}} 2. ^{{Harvnb|McDonnell|2002|p=145}} 3. ^{{harvnb|Solomon|2012|p=160}} 4. ^{{metrarail.com/about-metra/newsroom/the-signal/metra-powerhouse-f40c}} References{{commons category|EMD F40C locomotives}}
