A Letter to the Kensington Canal Company on the Substitution of the Pneumatic Railway for the Common Railway by Which They Contemplate Extending Their Line of Conveyance

"A Letter to the Kensington Canal Company on the Substitution of the Pneumatic Railway for the Common Railway" by John Vallance is a technical proposal advocating for a cutting-edge transportation solution. Aimed at the Kensington Canal Company, Vallance's letter champions the use of a pneumatic railway system, driven by air pressure, as a superior alternative to expanding traditional railways or canals between Kensington and the Grand Junction Canal. He meticulously argues that this innovative technology would offer significant cost savings by minimizing the need for extensive land alterations, like cuts and embankments. Vallance further suggests that the pneumatic railway promises faster transport of both goods and people, all while being less intrusive to surrounding landowners, ultimately positioning it as a financially sound and forward-thinking engineering endeavor ready to defy conventional expectations.
