. "GWR 1854 is a class of tank locomotive designed by William Dean and constructed at the Swindon Works of the Great Western Railway. The class used similar inside frames and chassis dimensions to the 1813 Class of 1882-4. In this they differed from the intervening 1661 Class, which had reverted to the double (\"sandwich\") frames of the Gooch and Armstrong eras."@en . . "Great Western Railway 1854 class"@en .
