This set includes the windows for the Prince Edward Island Railway/ CNR 1904 Standard Booking Station. For reference, the large 6/6 single windows scale out to 86" tall X 48" wide over the trim.
These stations were built at eight locations on the Murray Harbour branch in 1905: Hazelbrook, Vernon, Vernon River, Grandview, Melville, Wood Islands, Murray River, and Murray Harbour. A station was built at Montague Bridge in 1906, and a slightly modified station was built at Elmira, the easternmost point on the PEIR, in 1911.
The last of its type built, Elmira had a high window on the baggage room end. The others were all built with a blank baggage room end wall and three brackets. This window is included for those building a model of the Elmira station.
Full details on the PEIR structures can be found in my article in the July 2011 Model Railroader Magazine.
These parts can also be used to build a number of Intercolonial Railway of Canada/ CNR stations.
