The Oak Park Society of Model Engineers H.O Scale Model Railroad Club. Oak Park Illinois USA. July 2011., a photo by Eddie from Chicago on Flickr.
One of the really nice models to be seen on the large club layout at The Oak Park Society of Model Engineers H.O Scale Model Railroad Club, is this model of a steel girder swing bridge found on many of North America's waterways.
I always enjoy taking club layout photos and videos here, because this bridge reminds Me of the many that are still standing ( but long decommisioned) on the Chicago Sanitary and Ship Canal on the near southwest side of Chicago Illinois.
