Additional frame details:
“Vertical cast steel frame cross-ties are applied to front legs of the forward driving-wheel pedestals and to the rear legs of the second and third pedestals.  The forward brace includes an extension on the bottom, which is bolted to the lower frame rails just behind the cylinders.  This carries the pivot for the front engine truck and the driving brake lever fulcrums.  The top rails are further secured by cast-steel deck braces, which extend across the frames between the first and second, and the third and fourth pairs of driving wheels.” (First U.S. Standard Locomotive, Railway Mechanical Engineer, Vol 92, No 8, August  1918, pgs 436-438)
