Hi everyone.
I was wondering if the fancy shrouding is covering a Belpair fire box? The backward cylinders probably suffered the same problems as PRRs Q1.

I assume you are talking about the 4-4-4-4 5600 “George H Emerson”.
The firebox was a three drum water tube firebox, as applied to a number of B&O locomotives about the time they built the Duplex. It was known, on the B&O anyway, as an “Emerson” firebox.
The firebox was generally like the marine three drum boilers of the Yarrow or Admiralty type. The raised casing was to clear the top steam drum. Some B&O Emerson fireboxes had square cornered casings that did look like a Belpaire box but the 5600 did not.

Thank you.
That was the loco I was asking about. The water tube boiler was not very common on a steam locomotive. I think the B&O put one on a Pennsy K4 as an experiment.
How long was the 5600 in service? Was the performance what the designers thought it should be? Did it suffer from slippery drivers like the Pennsy T1?

I would have to dig around to find this out, but I doubt they used a Pennsy Pacific to experiment on, when they had their own P7 Pacific which was a far superior locomotive to the K4.
The B&O P7 #'s 5310 & 5320 were converted to full water tube boilers at the Mt Clare shops. In addition, the rest of the B&O P7 fleet was constantly upgraded as new technologies became available, and they lasted to the end of steam on the B&O.
