This batch of Atlantics (works numbers 30916-30921) represented typical high-speed engines of the time. Compared to other US 4-4-2s, these had relatively generous firebox areas, smaller than average grates, and about average evaporative heating surface area. The driving and engine wheelbases ran toward the top of the range while the adhesion and engine weights came in around the median. Likewise, tractive effort also met the median.
