Matthew Teller is a Head of Systems Integration (ERTMS) - at Govia Thameslink Railway at GTR (Govia Thameslink Railway). He possess expertise in train planning, railway. Colleagues describe him as "My first contact with Matthew was when he chose to spend a "gap-year" as an STP train planner prior to commencing his degree. Since then, during vacations, as well as train planning he has worked alongside the TPU in operations and engineering interface areas such as developing berthing provision. Matthew is an individual highly committed to the industry who it is both a privilege and pleasure to have within ones team and see his development thereafter. His periods within both the operations and engineering functions means he can see railway issues from both perspectives being able to identify corporate solutions that recognise the constraints and capabilities of different departments. " and "Matthew has worked for me over two summer vacation periods. On both occasions his work was excellent. His level of understanding of the railway, ability to research to find answers and capability to progress issues through to far exceed the expectations of someone with his level of career experience. Despite not yet having an engineering qualification I would readily have Matthew working as a full time project engineer or similar role. His comprehension of both the engineering and operational aspects of the railway mean that he will do very well in his future on the railway, and I am certain his work and career will benefit the railway industry as a whole.
