To successfully clear the Railway Recruitment Board (RRB) Technician Grade-I Signal examination under Centralized Employment Notification (CEN) No. 02/2026, candidates must possess a comprehensive understanding of the prescribed syllabus and examination pattern. The Technician Grade-I Signal position is a Level-5 post under the 7th Central Pay Commission (CPC) carrying an initial pay of Rs. 29,200/- per month. Because this post involves critical signal maintenance, telemetry, and electronic safety operations, the Computer Based Test (CBT) evaluates advanced scientific concepts, computer fundamentals, and technical reasoning.

The selection process for Technician Grade-I Signal comprises a single-stage Computer Based Test (CBT), followed by Document Verification (DV) and a B-1 Medical Fitness Examination. Below is a detailed, section-by-section breakdown of the official syllabus, subject weightage, negative marking rules, and preparation strategies derived directly from the official CEN 02/2026 notification.
