Way back when at one of the Frisco Modelers Information Group (FMIG) meets in St. Louis, MO, Joe Collias showed a movie of Frisco and Missouri Pacific stuff. It included a color scene of one of the Meteor 4500s at Grand Avenue.
That video film is available on Heron Video's "St. Louis Glory". It notes "From the collection of Joe Collias". The film has quite a few Frisco run bys as well as Missouri Pacific and other St. Louis railroads. Tom G.
