The 2-6-6-4 was a fairly late development, a product of the superpower steam concept, introduced by the Lima Locomotive Works, which encouraged the use of large fireboxes supported by four-wheel trailing trucks. Such a firebox could sustain a rate of steam generation to meet any demands of the locomotive's cylinders, even at high speed. High speeds were certainly among the design goals for a 2-6-6-4; most of the type were intended for use on fast freight trains.
Sabathia is taking credit for the home run barrage that was on display in The Bronx on Saturday afternoon ... The correlation was obvious — at least to Sabathia. B2B2B 💣s after my first pitch…coincidence? 🤣— CC Sabathia (@CC_Sabathia) March 29, 2025.
