America The vast majority of roundhouses built in the US and Canada no longer exist, lie in ruins, or have been repurposed; however, a small number of them still exist and continue to operate in their intended capacity as locomotive storing and servicing facilities. Of the roughly 3,000 roundhouses that once existed in North America, fewer than 200 roundhouses are extant in the US ; in Canada, none exist east of Montreal. Below is a list of locations with operational roundhouses that are also open to the public.
