Data from Apercu des Chemins de Fer Russes Depuis l'Origine Jusqu'en 1892, Editor in Chief Andre de Gortschakov (Brussells: Paul Weissenbruch, 1897).
These cross-compound Ten-wheelers were the brainchild of the President of Administration (direct & clumsy translation) of the Wlaw, J J Kerbedz. He saw the need for increased speed and heavier trains over a line that had many grades of 1% or more. In devising the leading bogie, the engineers created an arrangement that allowed negotiation of 266-meter curves.
