    This procurement process is being advertised and run by First Greater Western Limited on its own behalf and on behalf of the successor operator of the rail passenger transport services in respect of Great western Railway.

Where the transfer is not yet completed by the time of contract award, contractual rights may be included in the contractual arrangements to enable transfer to the successor operator. Bidders should note that this procurement process (if ongoing), or any awarded contract, may be included in a transfer scheme made by the Secretary of State under section 12 of the Railways Act 2005, or the transfer may be effected outside of, or separate from, such a scheme.​

All references to First Greater Western Limited shall be deemed to refer to the successor operator for the purposes of this procurement and the successor operator shall be entitled to continue or terminate this procurement as if it was involved from the outset.
