It appears that these new-fangled railways are here to stay, displacing the passage-boat and the mail-coach, the Scotch cart and the lumber boat.
Accordingly, I have rearranged my small number of railway-related pages under a top-level heading of their own.
I have added a new railway page, about the Lundy Island Railway and Colonization Company, from the Dublin Evening Mail of 2 May 1845. Gerald M King has produced stamps for Lundy, including Railway Parcel Stamps, but it is not clear whether they depict any of the engines or rolling stock described in the Mail and there are few other sources of information about the railway.
I have tried to explain as many of the references as I could, but some are still obscure to me and I would welcome comments from those expert in Irish religious conflicts of the 1840s (as well as those knowledgeable about railways and other technology of the period).
