The builder's photo of the unstreamlined J3a class shows the recessed Elesco feedwater heater on No. 5405. However, later photos of it and the other J3s, such as No. 5439 above, reveal that the Worthington type was applied in a subsequent shopping (note the box-like structure ahead of the stack). The 14-wheel "centipede" or pedestal type (PT) tender was another later addition, dramatically reducing the locomotives' need to take on coal during a run (water was replenished from track pans). Two members of the 1937 J3 group, Nos. 5426 and 5429, were streamlined for service on the Empire State Express. This photo by an unknown photographer is from my brother David Leonard's collection; it was taken in Cincinnati in September 1954. In the Mark I video The Midland and Two Centrals No. 5439 heads the all-stainless-steel James Whitcomb Riley in April 1955 at Kankakee, Illinois.
