On September 9, 2022, Austria, Liechtenstein and Switzerland joint efforts to release together a se-tenant souvenir sheet with three stamps dedicated to the 150th anniversary (1872-2022) of the railway connection Feldkirch – Schaan – Buchs (earlier information provided by Cesar Ittmann, the Netherlands).
Each country issued the same souvenir sheet but with perforation limited to the country’s stamp and denomination only on this stamp. In parallel, a se-tenant souvenir sheet containing the three stamps, all perforated (see illustrations below) and with the three denominations, two in CHF, one in Euros, was issued. On September 9 and 10, 2022, the train made the connection between the three places with a possibility to obtain a special cancellation from a post office installed at each station, allowing creation of triple mixed FDC covers. Stamps feature three locomotives from different eras used in each of the nations: a 1927 steam engine for Austria, an electric ÖBB traction unit from 2004 for Liechtenstein and SBB’s legendary Re 4/4 II built between 1964 and 1985.
