Metra EMD F40C No. 601 leads a westbound commuter train past Tower B17 at Bensenville, Illinois, on March 3, 1990. Similar looking to Amtrak’s SDP40F, the F40C has unique corrugated side panels and is built on a standard SD40-2 platform. Bought for commuter service on Milwaukee Road lines out of Chicago, a total 15 3,200 hp F40Cs were built by EMD. The first 13 units were bought by and lettered for North West Suburban Mass Transit District, while the remaining two were lettered for North Suburban Mass Transit District. All 15 spent all their lives working the lines west to Elgin and Fox Lake, eventually working under the Chicagoland commuter authority Metra.
