The only BR&P Decapods, these had very small drivers for pusher service; the class was later superheated - see Locobase 9616. On the B&O they retained the Y, but were renumbered 6500-6507.
Locobase isn't sure when the BR & P updated the Decks it had bought in the teens (see Locobase 2067). The revision was confined primarily to the boiler, which surrendered the usual sheaf of fire tubes in favor of larger flues. The firebox heating surface included 30.2 sq ft of arch tubes.
The result was a drier drag-freighter that served the BR & P and the B & O until 1950.
