Although stage coach companies were the first to use early American railroads to carry mails under contract in the early 1830s, it was not until 1838 that railroad companies were contracted for this service. In that year, all railroads were designated “Post Roads”. The development of services initially using Route Agents to accompany the mails developing to Railway Post Offices introduced widely in 1864 are illustrated using covers bearing a wide range of railroad markings.
