Was the Metropolitan Railway founded by American investors and therefore using American railroad terminology?
Short answerNo; its major early backing was British, and its terminology arose from local construction, purpose, and figures such as Charles Pearson.
NotesAmerican investors did not found the Metropolitan Railway or supply its original terminology. The Great Western Railway, Great Northern Railway, and City of London Corporation were the major early backers, each contributing roughly two hundred thousand pounds in this account. The line opened in 1863 and remained a distinct railway until the 1933 reorganization. Its language came from construction, intended function, and Charles Pearson's phrasing. Charles Yerkes's involvement around 1900 belongs to a later phase.
