Pennsy's Home-built class GLa hoppers in HO Scale from Bowser Pennsylvania Railroad's first all-steel hoppers were built in 1898 by Pressed Steel Car Co. but design flaws and production backlogs convinced Pennsy to construct their own improved version - the home-built GLa class. These hoppers became a PRR standard with over 30,000 built between 1904 and 1920. The cars lasted into the 1960s and a few remained in work train service into the 1980s. The GLa class was one of the most common coal hoppers in North America, so they'll look right at home on your steam- or early diesel-era layout. Ready-to-run GLa Hoppers from Bowser come equipped with knuckle couplers, metal wheels and feature authentic paint schemes.
