Course Details

The first step towards achieving your Negative Short-Circuiting Device (NSCD) Operator qualification is to gain experience and knowledge of working on the Railway as a PTS DCCR Operative, performing Level B Strapping duties. Negative Short-Circuiting Device (NSCD) Operator enables you to assist in the isolation process for a possession. You can attend the Negative Short-Circuiting Device (NSCD) Operator Course on your chosen date when you are ready to progress. Prior to attending the course, you will need to complete an online pre-qualifier eLearning Emergency First Aid knowledge check, which generates a certificate of achievement that you can print and bring on the day of your course and is valid for 5 years.

Your Railway Medical needs to be in date with a current Drug and Alcohol test. If you change Employer/Sponsor, you will need to take a new Drug and Alcohol test; contact us to book an appointment prior to attending your course or book online.

The qualification lasts for 5 years but to maintain your NSCD-Negative Short-Circuiting Device Operator competency, you will need to continually hold Level B Strapping on your Sentinel. Leading up to expiry, you can book an NSCD-Negative Short-Circuiting Device Operator Refresher Course.


Sentinel Track Safety cardholders, including DC isolation staff, range from all types of construction workers including Trackworkers, Tradespeople, Scaffolders, Engineers and Surveyors. The Railway has an excellent safety record with a focus on training, allowing you to progress and take higher-level courses. The natural progression from Level B is to attend an ES course then join the Safe Work Leader 2 programme.

Many people take a temporary job on the Railway but end up staying within the rail industry for the rest of their career. For the next 10 years, the Government has released a huge amount of money to maintain and enhance the rail network in the UK; for example, the first phase of the High Speed 2 project has created an additional 16,000 Railway jobs.
