both their kits and crest and the team itself retained only four players from Lokomotiv, with the core of the squad being players from Slavia-Chengelov. More than two decades after the 1928 earthquake, the fans of what was once Sportclub again had a home ground – the stadium of Lokomotiv. Changes in the formal names of clubs in the Soviet Union took place and a popular name for Eastern bloc sports clubs at the time, Torpedo, was adopted and the team was thus renamed Torpedo Plovdiv. For the 1950 season, Torpedo Plovdiv took the place of Slavia-Chengelov at the top level of the Bulgarian football league system (A RFG). National policy then required that, as part of the railway union, all club members and players had to be members of the union. This included former members of Slavia-Chengelov, who had no connection to the railways. Before the 1951 season began, the railway union established a new club, DSO Lokomotiv (Plovdiv), which shared Torpedo's colours and stadium. Torpedo's players were transferred to DSO Lokomotiv, and in order to make them official union members each player was nominally employed by the national railways. Meanwhile, Torpedo Plovdiv was removed from the labour union and no longer funded by it or the railway company. DSO Lokomotiv also acquired Torpedo's license to play in the top tier of the Bulgarian football league, while Torpedo was relegated to the third division. The labour union thus effectively legitimised the new club without needing to limit the access of the members of Torpedo to the sports facilities. Existing members of Torpedo could still use the shared facilities and were no longer required to be members of the railway union. As of 1951 the fans of Torpedo Plovdiv from 1950 now found themselves supporting the same players, with the same colours, in the same stadium, under a new name. As official membership in the club now required a job with the railways, the official number of members was drastically smaller than in previous years. Nevertheless, the supporters of the team remained the same. Hence, in 1951 DSO Lokomotiv effectively became the successor to Torpedo while Torpedo still competed at a lower level. From 1951-1954 DSO Lokomotiv was one of the best performers in the Bulgarian football elite, annually reaching at least the quarter-final phase of the domestic cup competition (at that time the Cup of the Soviet Army) and
