Mike Bartels wrote on March 18, 2021 -- "M-23 and M-24 and a trailer each were painted in Streamliner colors for the Capital Cities Flyer, inaugurated between Lincoln, Neb., and Topeka, Kan., in 1935. It connected with the Streamliner M-10000 in Topeka for Kansas City. It was discontinued between Marysville, Kan., and Topeka in 1938. Have seen pictures of the M-23 later repainted back to dark green. The carbody sat on a lot in Grand Island, Neb., until late 1969 when it was dismantled."
