Supt., are equipped with Street stokers; whilethe last ten, including the 4038, arefitted with Hanna stokers. The engineshave a large number of interchangeabledetails, and constitute a notable groupof heavy motive power units. The firebox, in this design, is placedback of the driving wheels and over therear truck, and has a combustion cham-ber 28 ins. long. The crown and sidesof the firebox are in one piece with thecombustion chamber, and the seam onthe bottom center line of this chamberis electrically welded. The tubes arewelded into the back tube-sheet. Ac-cess to the interior of the boiler is ob-tained through a 16-in. opening underthe auxiliary dome. The main frames are vanadium steelcastings, 6 ins. wide, spaced 42 centers. The CommonwealthSteel Companys back frame cradle
