Řazení ČD pro GRAPP is a free Chrome add-on developed by Kate Miháliková. This add-on adds the current train composition information of České dráhy (Czech Railways) to the GRAPP application. By using data from the ČD eshop, the train composition information is always up-to-date.

With Řazení ČD pro GRAPP, users can easily access the train composition information in the "Informace o vlaku" (Train Information) tab, both for the current and default (border) stations. Additionally, in the "Detail jízdy" (Journey Detail) tab, hovering the mouse cursor over the train icon will display the train composition for that specific station. The train icon color also changes when the train composition is updated.

This add-on provides a convenient way for GRAPP users to access accurate and real-time train composition information from České dráhy. With its seamless integration into the GRAPP application, Řazení ČD pro GRAPP enhances the overall train travel experience.
