Not exclusively "railways" in this gallery but I've included this selection of photographs taken by Mark Cameron (and passed on to me as part of the family holiday and wedding collection) as they depict subjects of interest to me and relevant to my hobbies. With just so much to see and do, we never actually made it to the Power House Museum but after reviewing Mark's photos, I would certainly try and get there on any future visit to Sydney - it looks a very interesting place.
