Trusted by major rail organisations

Our trainer Scott was really amazing. The pace with which he took us through the course was really good and he always ensured everyone was on board before proceeding. The examples used were relevant and easy to understand. All questions were answered in depth and where clarification was needed Scott provided it. I really enjoyed the course

IST Intermediate Signalling Technology

Trevor is a very dynamic trainer. It was a great run through the whole of signalling - and all the kit!

Practical Signaling Investigation

Reuben is fantastic and such a great teacher. He could explain almost anything in a very digestible manner. Best course I've attended by far.

Level Crossing Design

Trusted by major rail organisations

The course was delivered really well and I gained extra knowledge of data link system. The tutor, Reuben, delivered the material with a very engaging descriptive method. I learnt a lot about issues concerned with data links. I enjoyed learning about scope connections and how to set up test equipment. The course overall was very intuitive and enjoyable. It was a great first principles course taught by a very enthusiastic instructor.

SSI Data Link Testing Course

I learned about the background of ERTMS and how it relates to existing signalling methods. Several of the exercises were very useful. The course overall was very clear and easy going. The course provided a very clear presentation and overall. A huge learning curve for me a lot of background information was good as a refresh. The course gave me an insight to ERTMS technology and additional background information.

ERTMS and CBI Course

It was great course as I had very little knowledge of crossings before I started and left with a great understanding due to the tutor passing on his knowledge in a clear and simple way. The opportunity to practice fault finding and function testing of the circuitry was most beneficial to me. The course was very interesting with lots to learn and mitigating circuits. Very enjoyable and the course expanded my knowledge

Mod 3BX Level Crossing

Signet were able to arrange the course at a London location and tailored it to London Underground Standards. The trainer was very aware of the Standards and was very aware that certain things were done differently on LUL. The trainer delivered the course at a good pace. It was good to see how Network Rail work and about their developed process in comparison to our London Underground Standards. The group discussions were very useful regarding the standards to understand their meaning. The tutor was perfectly fitted. It will help me to develop in my career.

Mod 1 LUL

I enjoyed the interactive nature of the course. The instructor gave clear delivery and the information gained was very relevant to my job role. The instructor shared a lot of real life stories which were very interesting. He was clear, engaging, interactive and very knowledgeable. The course gave a great overview and was extremely helpful. The instructor was awesome and very knowledgeable and easy to understand. I enjoyed the course overall but relay and solid state interlocking logic appealed to me the most.
