General Knowledge questions frequently test awareness of Indian Railways' major digital and IT initiatives — systems candidates likely already interact with in their current supervisory role, but rarely stop to name formally.
Major Systems to Know
- CRIS (Centre for Railway Information Systems) — the PSU responsible for developing and maintaining most major IR digital platforms, including PRS, FOIS, and the HRMS module used for LDCE/Selection applications.
- FOIS (Freight Operations Information System) — tracks freight wagon movement, rake management, and freight billing across the network.
- COIS/NTES (Control Office / National Train Enquiry System) — provides real-time train running status and section control information.
- PRS/UTS — Passenger Reservation System and Unreserved Ticketing System, the two core passenger revenue systems.
- HRMS (Human Resource Management System) — the platform through which LDCE/Selection applications, e-call letters, and increasingly PYQ/answer-key access are handled.
Exam Focus
Expect matching-type questions pairing a system acronym (FOIS, PRS, COIS, HRMS) with its correct function — precise recall of what each system actually does is more commonly tested than deep technical detail.
