About this app
Railway signs and signals reference with drills and identification quizzes.
Read full description
Railway signaling depends on shapes, colors, and positions that repeat across systems. Browse a catalog of signs and aspects, filter by category or operating system, and open entries with meaning, context, and related signals. Quiz packs and daily drills test whether you read the line quickly under pressure. Track scores across packs, revisit missed aspects, and move from a wrong answer back to the reference entry that explains what you overlooked.
