In order to encourage more people to take the train, postage stamps were for a time accepted as train tickets. This saved the potential rider from making a special trip to the train station to buy a ticket. Trains moved so slowly then that they could be waved down to pick up passengers practically anywhere along the tracks.
為了鼓勵起見，當時還准許用郵票代替車票，省去乘客到站買票的麻煩，所以當年郵票上都印有「可通用火車票」的字樣。
