Arnab Dutt, managing director of Texane Ltd, is a public member of Network Rail - one of the people holding the board to account for its leadership and management under the company's unique governance structure. Safety is one of the key factors he has to take into account.
"Britain's railways are getting busier. While networks continue to grow to keep up with the population and their demands, safety remains as important as ever.
"When we talk about keeping safe on our rails, we're not just talking about the rail workforce, but passengers and pedestrians too. We need to address safety in different ways to suit the needs of everyone who works, uses, lives near or even passes by our railways."
