LOCAL RAILWAYS OF MACEDONIA: After the end of WWI, the French forces, which had constructed the Skidra - Aridea - Orma network, left the lines and rolling stock to the Greek state. On 10 August 1923, the Greek state signed a concession agreement with Ep. Charilaos for the operation of the line with a validity of the line for 50 years, beginning on 29 August 1923. On 5 February 1924 the Topiki Sidirodromi Macedonias (TSM) were founded, with a share capital of 10.000.000 drachmas divided into 100.000 shares with a nominal value of 100 drachmas each. During the short duration of its operation, the network became known as "The Karatzova Train". In 1929 the company declared a Lock-Out and in 1932 the operation of the network was undertaken by SEK.
