Postal wagon Stamp Day 1951
Postal inspector in Alsace, François Donat Blumstein (1795-1879), proposed to the Administration to organize the transport of mail by rail.
On August 1, 1842, he put his idea into practice on the line from Strasbourg to Basel.
But the project received little support from the general director of posts, Antoine Conte, on the grounds that mobile offices do not exist anywhere.
Blumstein, at the invitation of Belgium, then entrusted his organizational plan to the Belgian postal administration.
The experience proving conclusive, France plans to adopt Blumstein's plan.
The latter will be sent in 1845 on the Paris-Rouen line for the implementation of traveling offices.
The first model of wagon put into service in 1845 is 4.80 meters long and 2.40 meters wide.
During the trip, handling and sorting operations were carried out, until then carried out entirely by post offices.
Built of wood, this traveling post office prohibited the use of stoves or heaters likely to start a fire.
This is why the railway company provided balls or metal boxes of boiling water in winter.
