RRB Technician Grade 1 Signal Eligibility 2026

RRB Technician Grade 1 Signal eligibility depends on three things: a science or engineering qualification from the approved list, an age between 18 and 33 years on the reference date, and fitness for the B1 medical standard. The rules below follow the CEN 02/2026 notification as reported, and they will help you decide quickly whether you can apply in this or a later cycle.

The application window for CEN 02/2026 closed on 29 July 2026, so this page also works as a checklist for the next Technician notification. Always confirm the exact cut-off dates in the notification of the cycle you are applying for.

Eligibility at a glance

Educational qualification

Candidates must hold one of the following:

• B.Sc.: A degree with Physics, Electronics, Computer Science, Information Technology or Instrumentation, or a combination of these subjects.

• Diploma: A three-year Diploma in Engineering in a relevant stream.

• Degree: A Degree in Engineering in a relevant stream.

The qualification must be complete on or before the cut-off date in the notification, reported as 29 July 2026 for this cycle. Final-year students whose results are awaited cannot rely on a provisional result unless the notification allows it.

Grade 1 and Grade 3 are different

Technician Grade 3 uses a Matriculation or SSLC plus ITI or Act Apprenticeship route. Some pages mix the two grades and show ITI as the Grade 1 qualification. For Grade 1 Signal, use the qualification list above, and read the exact wording in the notification annexure.

Which streams count as relevant

The notification lists the relevant engineering streams for each post. Electronics, electrical and instrumentation branches are the most commonly accepted for signal work, but the final list is in the notification. If your branch is not clearly listed, check with the RRB helpdesk before you apply.

Age limit and relaxation

The age limit is 18 to 33 years as on 1 July 2026. This gives a date of birth on or after 2 July 1993 and on or before 1 July 2008 for general candidates. Upper-age relaxation is added for eligible categories as per government rules.

These are the standard Railway recruitment relaxations as reported by secondary sources. Serving railway staff and widowed or divorced women have separate age limits in the notification. Check the official notification before claiming any relaxation, and keep the supporting certificate ready.

Medical standard and other conditions

• Medical standard B1: The post is under the B1 category, which includes vision tests. Colour vision and visual acuity standards are set by the Railway administration and are listed in the notification.

• Citizenship: Candidates must meet the nationality conditions in the notification.

• Region: You apply to one RRB, and the language of the paper and your posting preference depend on it.

• Government employees: A no-objection certificate is needed at document verification if you are already in government service.

Who is not eligible

• Candidates whose qualification is outside the approved list, for example a B.Com or B.A. degree.

• Candidates who do not complete the qualification by the cut-off date.

• Candidates outside the age window after applying relaxation.

• Candidates who do not meet the B1 medical standard.

• Candidates whose category certificate is invalid or in the wrong format.

Application fee and documents

Refunds are reduced by bank charges. At document verification, bring originals of the Matriculation certificate, your qualification certificates and marksheets, category certificate where needed, and a photo ID, along with the self-attested copies required by the call letter.

How to check your own eligibility

1. Match your degree or diploma subject with the approved list.

2. Calculate your age on the reference date and add any relaxation.

3. Confirm your qualification result date is before the cut-off.

4. Check the B1 vision standard with an eye test.

5. Read the notification for your RRB before applying.
