Dick Hovey of Fayetteville, Ar discovered this example of the 20000 - 20424 series type XL boxcar while out riding the new trail extension on the South side of Fayetteville, on the property of Ozark steel. Thanks to Dick and Steve Marquess for sharing. Photos from Dick Hovey. In 1969 and 1970, the Frisco leased 425 equipped forty foot boxcars from Chicago Freight Car. Like the previous Kellogg cars, these were also equipped with DF-2 loaders and belt rails except they had nine foot Youngstown corrugated doors. These cars were mostly assigned to specific shippers, for example; US Gypsum in Southard, OK and Scott Paper Co. in Mobile, AL. Note the black background coonskin and serif reporting marks and number, with the white - only "Ship it on the Frisco" slogan. Thanks to Nick Molo for the detail info.
