In December 1918 Czechoslovak troops occupied the town and Czech railway employees took over the running of the depot and the administration; the former Hungarian state line passed to the Czechoslovak command, while the private Košice–Bohumín company was directed from Košice. There were not enough flats for the staff, so in 1921 the railway employees founded a building and housing co-operative, and with it came the Workers' House, the Sokol hall, a municipal building and a fire station. The banks of both rivers were regulated during the same building boom, which finally reduced the flooding. After 1930 a battery factory and a Catholic cultural house were added, the Catholic church was completely rebuilt and the Lutherans, who had built a new church in the years around 1900, added a cultural house in 1943.V decembri 1918 obsadilo mesto československé vojsko a správu depa i železnice prevzali českí železniční zamestnanci; bývalá uhorská štátna trať prešla pod slovenské veliteľstvo ČSD, súkromnú košicko-bohumínsku dráhu riadilo riaditeľstvo v Košiciach. Bytov pre zamestnancov nebolo dosť, a tak v roku 1921 založili železničiari stavebné a bytové družstvo; s ním pribudol Robotnícky dom, sokolovňa, obecný dom a hasičská zbrojnica. Počas tej istej stavebnej horúčky upravili brehy oboch riek, čo napokon zmiernilo povodne. Po roku 1930 pribudla továreň na baterky a katolícky kultúrny dom, katolícky kostol úplne prestavali a evanjelici, ktorí si nový chrám postavili v rokoch okolo prelomu storočia, si v roku 1943 pridali kultúrny dom.
