OREANDA-NEWS. A Network Rail spokesperson, said: "We are sorry for the problems that have affected train services on the Great Western Main Line this week. Performance has been well below the standards passengers deserve and expect.

"We are acutely aware of the frustration and inconvenience felt by passengers when things go wrong. We are working constantly across the rail network to improve the reliability of train services, investing billions over the next five years across the West's rail network to improve signalling, replace old equipment and bring in new modern technology and new trains to provide more reliable train services.

"This week we have not been able to provide the reliability passengers expect for which we apologise. We are wholly focused on delivering a new, modern, reliable rail network for London and the West. "
