Fairbanks Morse's Consolidation line showed great promise early on and secured multiple orders from several railroads. Only five signed up for the 4-axle version, but most of those that did went back for more. The locomotives were available in multiple horsepower configurations and with several options like dynamic brakes and steam generators for passenger service. Their rounded lines were as distinctive as the sounds from the FM opposed cylinder diesel engine. And although these 4-axle versions were generally purchased for freight service, some did see passenger roles as well.Ultimately, the FM engines were not the reliable workhorses the railroads expected. Some, like the New York Central, remotored their C-Liners with EMD blocks to extend their lives. Others worked the engines as long as they could and retired them quietly in the early 1960s. For Lionel's second C-Liner run, we're featuring these 4-axle locomotives for all of the roads that owned them. Stand out details include the Mars lights on the Milwaukee Road units and the Pennsylvania's trainphone radio antenna. Models are also available for the first time with 4-digit addressing and SuperBass B units! All A and B units are available separately so you can run these as you wish - a classic A-B-A configuration or mixed and matched with other locomotives. A units feature front ElectroCouplers and non-operating rear couplers for better close-coupling. The B units feature a non-operating front and rear ElectroCoupler. These locomotives are sure to add some character to your roster as a stand out from all of those EMD and Alco covered wagons.
