Major track work on the railway corridor linking Prague with eastern Czech Republic and Moravia begins Thursday, causing disruptions to train services. Until mid-September, long-distance trains between Kolín and Pardubice will be restricted to single-track operation, potentially leading to delays for passengers. Czech Railways (České dráhy) will replace some regional train services with bus transportation along affected sections of the route. These limitations are necessary to facilitate ongoing maintenance and upgrades to the critical rail infrastructure. Travelers are advised to check schedules and expect longer journey times. The works aim to improve the long-term reliability and capacity of this important transport link. Passengers should prepare for possible disruptions and plan their travel accordingly.
