National Rail is buying a content management and storing system to runs its journey-planning website nationalrail.co.uk, which has an average of 18 million visits per month.
An invitation to tender is going out under its Train Information Services (TIS). The systems will need to be fully compatible with the existing front-end design of the website, said National Rail in a notice in the Official Journal of the European Union.
It will also need to interact with the existing journey planning services and live train information, currently provided on the website, as well as handle multiple updates done at one time.
The new service must be capable of handling normal daily load from users and any unexpected spikes in demand that are caused during periods of disruption on or around the rail network, said National Rail.
The contract will last for three years, with the possibility of a four-year extension. The body did not provide information about the potential cost of the system.
