'40s Junction

'40^s Junction is a commercial-free music channel on the Sirius XM Radio platform, broadcasting on channel 71; as well as Dish Network channel 6071. The channel mainly airs big band, swing, and hit parade music from 1936 to 1949, with occasional songs from the early-1950s. Until May 7, 2015, the station was known as '40^s on 4, with programming being broadcast on channel 4, as part of the "Decades" line-up of stations. It was later rechanneled to be nearer to stations featuring similar genres of music, such as jazz and standards. During its first four months on Ch. 71, the station was known simply as '40^s. The station was rebranded as 40^s Junction on August 13, 2015.

The 40^s Junction name, and the station's longtime nickname, "The Savoy Express", refer to the passenger train−travel common in the 1940s. The name also lends reference to the popular dance hall in Harlem during 1940s called The Savoy Ballroom, where the Lindy Hop and "Jitterbug" dancing was born. The original "Station Master" (Program Director) for the channel was Marlin Taylor, with Bob Moke serving as music director. Both have since departed, and the channel is currently programmed by Human Numan. The "voice" of the channel is Lou Brutus, who models his announcing style after that of Bing Crosby staff announcer, Ken Carpenter. Brutus worked as Sr. Director of Music Programming, overseeing the content for a long and diverse lineup of channels. He was subsequently laid off from SiriusXM amongst a company wide reduction of staff in March of 2023. In keeping with the railroad theme, the station's logo now features a train itself, based on the 1940s Reading Railroad's sleek stainless steel streamliner called the "Crusader", which operated between Philadelphia and Jersey City, NJ. Trains were the primary mode of distance transportation in the '40s. Airline travel wasn't fully developed and cost prohibitive to the masses.
