Railway GK Questions 2026

Static GK in railway exams starts with one shared block: Class 10 science. Every RRB exam on GK24 tests it. Group D has 25 questions on Physics, Chemistry and Life Sciences of 10th CBSE level. JE has 30 in CBT-1 and another 15 on Physics and Chemistry in CBT-2. ALP tests General Science in CBT-1 and Basic Science and Engineering in CBT-2, and NTPC lists general science up to 10th inside General Awareness. Beyond science, the lists differ. NTPC names history and the freedom struggle, geography, polity, the economy, art and culture, environment, computers, abbreviations, transport systems in India, world organisations and government bodies. JE names geography, history and culture, polity, the economy and environmental issues, and adds computers and pollution control in CBT-2. This page holds GK24's topic-wise GK notes for railway exams in English and Hindi: General Science, History, Geography, Polity, Economy, Art and Culture, Environment, Computers and static GK, including Indian Railways. Each note is short facts and tables that can be revised in one sitting. Begin with the science notes, since they serve every railway exam, then add the static topics your exam lists, and test each note with its quiz.
