The Railway Recruitment Boards (RRBs) have released the questions, candidate responses and provisional answer keys for the Technician recruitment under CEN 02/2026.

• Fee: ₹50 per question, plus bank charges. If your objection is accepted, the fee is refunded, minus bank charges, to the account you paid from.
• Payment: debit card, credit card, UPI or net banking.
• After 11:55 pm on 22 October, the RRBs will not take any representation on questions, options or keys. Their decision on objections is final.

How to read your score

Each test had 100 questions in 90 minutes, with one-third of a mark deducted for every wrong answer. When you tally your responses against the key, subtract a third for each wrong answer. Leave unattempted questions at zero.

The notice sets minimum qualifying marks: 40% for unreserved and EWS candidates, 30% for OBC (non-creamy layer) and SC, and 25% for ST. These can be relaxed by 2 marks for PwBD candidates if there is a shortage. Because the tests ran in several shifts, the RRBs will normalise marks, so your final score may differ from your raw count.

What to do now

1. Log in on your RRB’s website and download your response sheet before the window shuts at 11:55 pm on 22 October.
2. Score yourself with the negative marking applied.
3. Object only where you can back it with a reliable source, such as a standard textbook or an official specification. Each challenge costs ₹50.
4. Finish payment well before 11:55 pm on Thursday, 22 October.
