Osgood Bradley / Pullman Factory in Worcester, MA

I am trying to find out some information about the Pullman Standard factory in Worcester, MA. I know it was originally owned by Osgood Bradley, that they were bought out by Pullman in 1930, closed in 1960, and part of the structure burned in the early 2000's.

Beyond that, though, what did they build there? I know they built some PCC cars and trackless trolleys, but it also appears as though they built coaches as well. Was this a primary manufacturing location, or just to supplement other operations? What was the factory most known for, what was the most exciting things to come from there?

There is still part of the building - the old brick portion - still standing. Was that the main assembly building, or was most of the work done in the large wooden sheds that were consumed by the fire?

Thanks for any information of leads you can provide me!
