RRB JE 2026 in full: CEN 04/2026 is live with 4,029 vacancies and applications close on 13 September, plus the two-stage CBT pattern, category qualifying marks and an 8-week plan.
RRB Junior Engineer (JE) is the Railway Recruitment Boards recruitment for technical supervisory posts on the Indian Railways, under the Ministry of Railways. The same Centralised Employment Notice (CEN) also covers Junior Engineer (IT), Depot Material Superintendent and Chemical and Metallurgical Assistant, so one application window serves several post families. Selection is a two-stage computer-based test followed by Document Verification and a medical examination.
Yes. The Railway Recruitment Boards issued CEN 04/2026 on 13 August 2026, and the application window runs from 14 August to 13 September 2026 with fee payment open until 15 September 2026. As of September 2026 that closing date is days away, so read the deadline before you read the strategy.
| Event | Detail (CEN 04/2026) |
|---|---|
| Notification released | 13 August 2026 |
| Online application window | 14 August to 13 September 2026 |
| Last date for fee payment | 15 September 2026 |
| Vacancies after Corrigendum-1 | 4,029 |
| Vacancies as first announced | 3,993 |
| CBT-1 date | Not announced, expected December 2026 |
Vacancies stand at 4,029 after Corrigendum-1, up from the 3,993 announced originally, the addition being Chemical and Metallurgical Assistant posts that are new to this cycle. Eligibility is a 3 year diploma or a BE or B.Tech degree in the relevant discipline, with an age band of 18 to 33 years and the usual category relaxations. Exam dates have not been announced: December 2026 is circulating as an expected CBT-1 window and should be treated as expected, not fixed, until an RRB publishes the schedule.
RRB JE 2026 has two computer-based stages. CBT-1 is 100 questions for 100 marks in 90 minutes and only screens candidates. CBT-2 is 150 questions for 150 marks in 120 minutes and decides the merit. Both stages deduct one-third of a mark for a wrong answer, and the exam medium is multilingual, offered in Hindi, English and several regional languages.
| Section | Questions | Marks |
|---|---|---|
| Mathematics | 30 | 30 |
| General Intelligence and Reasoning | 25 | 25 |
| General Awareness | 15 | 15 |
| General Science | 30 | 30 |
| Total (90 minutes, 1/3 negative) | 100 | 100 |
CBT-1 shortlists about 15 times the vacancy for CBT-2 on normalised scores, and its marks are not carried into the final merit. That is why a comfortable, balanced clear matters more here than a spectacular score.
| Section | Questions | Marks |
|---|---|---|
| General Awareness | 15 | 15 |
| Physics and Chemistry | 15 | 15 |
| Basics of Computers and Applications | 10 | 10 |
| Basics of Environment and Pollution Control | 10 | 10 |
| Technical Abilities (your discipline) | 100 | 100 |
| Total (120 minutes, 1/3 negative) | 150 | 150 |
The first four rows are the common part, worth 50 marks and identical for every candidate. Technical Abilities is the discipline-specific 100 marks that actually separates the merit list.
RRB JE CBT-1 sets a category-wise qualifying floor you must cross before your score is considered at all: 40% for UR, 30% for OBC and SC, and 25% for ST. It is a floor, not a cut off, and in a competitive zone the real shortlist line sits well above it.
| Category | Minimum qualifying marks |
|---|---|
| UR | 40% |
| OBC | 30% |
| SC | 30% |
| ST | 25% |
Crossing 40% does not put you into CBT-2 by itself. Only the top candidates, up to roughly 15 times the vacancy, are shortlisted, so plan for a score comfortably above the floor rather than at it.
CBT-1 is screened on total marks across four sections, so a balanced clear beats a lopsided one. Mathematics 30 and General Science 30 are the two largest blocks and both sit at about class 10 standard, Reasoning 25 rewards pattern drills, and General Awareness 15 needs current affairs plus static GK and a little Indian Railways awareness.
Because CBT-1 marks are discarded after the shortlist, the goal is efficiency: finish 100 questions inside 90 minutes with a high strike rate and leave nothing risky on the table. Mathematics and Reasoning are where time is won or lost; General Science and General Awareness should be near-instant recall.
CBT-2 is decided by Technical Abilities, the 100 mark discipline-specific section. Bank the 50 common marks first, because Physics and Chemistry, computers and environment are small, finite and predictable, then give the rest of your preparation to the technical blocks.
The technical standard is diploma level: conceptual recall, standard formulae and direct application rather than derivation. Build one formula sheet per block and rehearse it until unit conversions are automatic.
Three wrong answers cancel one correct answer, so accuracy is worth more than volume in both stages. Attempt when you can eliminate options or apply a formula with confidence, and skip pure guesses. We ran this through our own scoring engine, which deducts 0.33 for each wrong answer rather than an exact one third: a CBT-1 attempt with 30 correct and 30 wrong scores 20.10 there, against the 20.00 an exact one third gives, and either way the gap down from 30 out of 100 is what decides who makes the 15 times shortlist.
Eight weeks works when your diploma fundamentals are intact. Technical Abilities deserves about half your daily hours from day one, because it is 100 of the 150 marks that decide merit.
| Weeks | Technical work | Non-technical work | Tests |
|---|---|---|---|
| 1 to 2 | First 3 technical blocks, formula sheet started | Mathematics and Reasoning basics | 2 sectionals a week |
| 3 to 4 | Next 3 blocks, numerical practice | General Science, Physics and Chemistry | 2 sectionals a week and 1 CBT-1 mock |
| 5 to 6 | Last 3 blocks, full formula sheet revision | Computers, environment, General Awareness | 2 CBT-1 mocks and 2 CBT-2 mocks |
| 7 to 8 | Weak blocks only, error log rework | Current affairs of the last 6 months | 4 CBT-1 mocks and 4 CBT-2 mocks |
Take at least 10 to 15 CBT-1 mocks and 10 to 15 CBT-2 mocks in your discipline, plus sectionals on your weakest technical blocks. Composite single-timer papers punish poor section pacing, and only full-length mocks expose that.
The Quiz4Exam RRB JE series is built on 1,973 original questions across 24 tests at 100% exclusive content. A full-bank blind audit covered all 1,973 questions and escalated 28 flagged or split items to a blind 3 solver panel, which applied 4 fixes and kept 24 as written, for a 0.20% true defect rate; all 996 technical questions were re-solved by 3 independent solvers with 996 of 996 keys confirmed; and a separate fact-check of 703 factual keys across General Awareness, General Science, Physics and Chemistry, computers and environment returned 0 wrong keys. A live scoring test then landed exactly where that engine predicted on both paths, including a CBT-1 score of 20.10 out of 100 from 30 correct and 30 wrong. Our engine deducts 0.33 for each wrong answer rather than an exact one third, which is why that figure reads 20.10 and not the 20.00 an exact one third would give.
Start with the free RRB JE mock test, then work through the full RRB JE CBT-1 and CBT-2 test series for Civil, Mechanical and Electrical, which we author in English and Hindi.
If you hold an engineering diploma you should also weigh the SSC route, where our SSC JE 2026 strategy guide explains a two-paper pattern with a very different negative-marking design, and candidates who want a second railway option this year can compare it with our RRB NTPC 2026 strategy guide.
Apply before 13 September 2026, then clear CBT-1 comfortably across all four sections and win CBT-2 on the discipline-specific Technical Abilities while banking the 50 common marks. Respect the one-third negative marking, drill your technical formulae, and finish with full-length timed mocks in your discipline.

Yes. The Railway Recruitment Boards issued CEN 04/2026 on 13 August 2026. Applications run from 14 August to 13 September 2026 with fee payment open until 15 September 2026. Vacancies stand at 4,029 after Corrigendum-1, up from the 3,993 first announced. Exam dates are not announced; December 2026 is only an expected CBT-1 window.
No. CBT-1 is qualifying and only screens candidates, shortlisting about 15 times the vacancy for CBT-2 on normalised scores. The final merit is prepared on CBT-2 alone, so CBT-1 needs a comfortable clear rather than a maximised score.
RRB JE CBT-1 sets a category-wise qualifying floor: 40% for UR, 30% for OBC and SC, and 25% for ST. Clearing that floor alone does not take you to CBT-2, because only the top candidates up to about 15 times the vacancy are shortlisted, so aim well above the minimum.
It is a 100 question, 100 mark section specific to your engineering discipline (Civil, Mechanical, Electrical and others). Alongside it sit 50 marks of common sections, so Technical Abilities is two-thirds of the CBT-2 paper and the biggest single determinant of your merit position.
One-third of a mark is deducted for every wrong answer in both CBT-1 and CBT-2, and there is no penalty for unattempted questions. Our own scoring engine deducts 0.33 for each wrong answer rather than an exact one third, so a CBT-1 attempt with 30 correct and 30 wrong answers scores 20.10 out of 100 there against the 20.00 an exact one third gives, and either way it shows how quickly loose guessing erodes a good paper.
