Would this United Kingdom train apparatus qualify as a catcher pouch from Travelling Post Offices in the United Kingdom?
If so, then it is not a unique mail bag used only by the United States Railway Post Office.
The article says in the History section: The first special postal train was operated by the Great Western Railway between London and Bristol. The inaugural train ran on 1 February 1855, leaving Paddington station at 20:46, and arriving at Bristol at 00:30. In 1866, apparatus for picking up and setting down mailbags without stopping was installed at Slough and Maidenhead.
So fix it. The article as I found it said "A catcher pouch was a unique mail bag used only by the Railway Post Office of the late nineteenth century and the early twentieth century." Since the article Railway Post Office is exclusively about a particular entity in the United States, and sources cited did not mention the use of this system elsewhere, I concluded that first sentence was intended to describe this as a system unique to the United States Railway Post Office. If the sentence (created by Doug Coldwell) whose meaning I clarified was inaccurate, don't blame me! --Orlady (talk) 19:10, 21 September 2012 (UTC)[reply]
