I've recently been reading up about a few of the names associated with early railway history, having in recent years expanded my interest from the railways of late Victorian times onwards... One name who crops up as an opponent of early railways is Dionysius Lardner, a gentleman who held views such as people being suffocated when passing through tunnels, as so much air would be evacuated by the train's progress. In reading up about Lardner, I came across this link to a report he published in September 1844, regarding a boiler explosion in Reading, USA. I thought it may be interesting reading, particularly in that the conclusion reached seems ridiculous, considering that the most likely cause is also discussed and rejected... https://books.google.co.uk/books?id...ce=gbs_ge_summary_r&cad=0#v=onepage&q&f=false It seems like an early form of deflecting blame, as Lardner had been conducting business with Norris, the Locomotive manufacturers. Hopefully, someone may find the link of interest... If not, I apologise for taking up bandwidth! Richard.
