If you wrote a Southern Railway departmental exam on 10 or 11 September 2026, the final answer keys are out. The Railway Recruitment Cell (RRC) in Chennai has put up the question paper and the final answer key as separate PDFs for 33 posts. DCBT is the computer-based test used in these departmental examinations, and the notice does not spell out its full form.
The Unit column shows the railway unit for each post. HQ is the Southern Railway headquarters in Chennai. The other entries are usual station codes: MAS (Chennai Central), MDU (Madurai), PGT (Palakkad), SA (Salem), TPJ (Tiruchirappalli), TVC (Thiruvananthapuram), GOC (Golden Rock), PTJ (Podanur) and CW/PER (Carriage Works, Perambur). The notice itself does not expand these codes.

Question Paper and Final Answer Key page (RRC Chennai)
Do not open the first PDF you see for a post name. Sr.Clerk/PB appears under seven different units, and each has its own papers.
Use the set letter that matches your own question paper. Set A, B, C and D are different versions of the paper, so the key for one set will not fit another.
Download from the official RRC page only. The RRC site itself warns candidates to beware of touts, brokers and job racketeers.
Check the RRC page again if something looks off. RRC says it can correct typing or other small errors on the page.
The page gives no objection window or fee for this final key, so do not assume one. Look at the RRC site for any separate notice.
