Boston and Maine Turntable

Hi, I am an industrial archeologist that excavated a roundhouse and turntable constructed by the B&M RR in 1888. We found a 2-x-3.25 ft projection off the south wall of the turntable that was 3.25 ft west of the lead track. A grate or vent and was found within the projection with wood framing dividing the space. I noticed on the Danbury Railway Museum's website a photo of their turntable with a similar projection. Does anyone know what these projections functioned as or what equiptment that they housed?

I believe this was to be able to access the wheels that ran on the pit rail.

Where is this turntable pit located?

This turntable was at Salem MA, for the North RIver 12 stall roundhouse that is now the site of the new parking garage.
