Hi. I grew up about 3 blocks away from the shops in West Burlington Iowa.The roundhouse was in this shop . My uncle worked there for 35 years and walked to work every day a few blocks. I believe the building is still there and it is Westinghouse Hill that is in West Burlington. The St. Marys Catholic church and grotto is right next door to the place. It is at the end of Spring Street and Hwy 34.I have a book about the RR in Burlington I could give you. I would have to locate it. Hope this helps. I'll see if I can remember any thing else.Linda
