Dear Emyl,
RE: Application for directions: proposed track access contract between Network Rail
Infrastructure Limited and Grand Union Trains Limited
This letter provides the representations of Network Rail, as requested in your letter of 22 June 2022,
regarding the application for directions for a proposed track access contract between Network Rail
Infrastructure Limited (Network Rail/we) and Grand Union Trains Limited (Grand Union).
We have worked with Grand Union on previous iterations of this track access application between
London Paddington and Carmarthen to identify capacity for potential paths and evaluate their
performance impact.
We submitted a detailed and comprehensive range of studies to assess the previous iterations of this
track access application. The following studies have been completed as part of our responses to the
previous track access applications between London Paddington and Carmarthen submitted by Grand
Union:
• Capacity analysis between London Paddington and Cardiff Central
• Platforming assessment at London Paddington
• Assessment including platforming at Cardiff Central and capacity between Cardiff Central and
Carmarthen
• Timetable performance microsimulation on the Great Western Mainline
• Supplementary path variance analysis on the Great Western Mainline to Cardiff Central
Unfortunately, we are not able to support this track access application due to significant operational and
performance concerns remaining unresolved. There is also a large amount of operational information not
yet clarified by Grand Union in their application. This is particularly important given the forthcoming
impacts on the Great Western Main Line and South Wales Main Line with the construction of new
stations at Old Oak Common and Cardiff Parkway, as well as the service revisions required to serve
them.
