The narrow-gauge railway Tehran – Rey, which started its operation in 1888, is Iran's first railway line. Initially planned as a horse-drawn railway, it was operated as the Decauville railway with steam locomotives. Railway operations were stopped in 1962. Today a metro line connects Tehran with Rey. Horse-drawn tram In January 1859 a Persian delegation travelled to Vienna on behalf of Naser al-Din Shah to conclude a consular treaty between Tehran and Vienna and to recruit talented craftsmen and engineers for the industrialization of Persia. Prime Minister Amir Kabir had started his reform and industrialization program and founded Dar o-Fonun in 1851, the first technical university in Iran based on the western model. The Austro-Hungarian railway engineer, Albert Joseph Gasteiger Freiherr von Ravenstein and Kobach (de) were approached and enthusiastically accepted the order to build a railway in Persia. He learned Persian language on Polytechnic Institute (de) in Vienna in 6 months [1], then he left Vienna on July 17, 1860 and reached Tehran on September 30. When he arrived in Tehran, he quickly realized that he had been mistaken in his opinion about the culture of the Persians. "In Europe at that time people still believed to find a country from the Arabian Nights here, but in reality it was a broken state that was completely devastated." [2] This was due to the apparent disinterest of the Qajar rulers to develop the country and instead only think about increasing their own wealth. In February 1861, Gasteiger began surveying a horse-drawn tram from Tehran to Shah Abdol-Azim Shrine in Rey, nine kilometers away, a much-visited place of pilgrimage. He calculated the cost of building the railway with a deployment of 1,000 men and a construction period of three months at 18,000 tomans. Gasteiger hadn't expected what would happen next. "A senior Persian official clapped his hands over his head and said that he had undoubtedly miscalculated and that the cost would have to be 30,000 tomans, otherwise it would be preferable to abandon the whole thing." [3] Gasteiger remained steadfast in his calculations and refused to include the bribes for the court official in his calculations, and so the railroad project was put on hold for the next 25 years. Concession and construction of the railway In December 1886 the project was offered to the French engineer Fabius Boital, who first signed a concession agreement with Naser al-Din Shah for
