The following cookie notice relates to the same legal entities as covered by the privacy notice.

General information

What are cookies?

In general, a cookie is a small amount of data (text file), which may contain a single anonymous ID code and which is usually sent from a web server of the website visited on the user’s device (computer, notebook, tablet, smartphone) to the web browsing software (browser) of the website visitor, to be subsequently re-sent to the visited website at the subsequent visit. The cookie is then read again and identified only by the website which has sent it whenever the user visits that website. When browsing, users may also receive cookies on their device which are then sent from other websites or web servers (the so-called “third parties”), which may contain some elements (such as, for example, images, maps, sounds, specific links to pages of other domains) present on the website the user is visiting.

Cookies may be used for various purposes: monitoring sessions, storing information on specific settings regarding the users who access the server, carrying out authentication processes, etc.

It is possible to define and classify them in various ways, for example by distinguishing between “technical” and “profiling” cookies.

  1. Technical cookies

Technical cookies are those cookies used for the sole purpose of “carrying out the transmission of a communication on an electronic communications network, or insofar as this is strictly necessary to the provider of an information society service that has been explicitly requested by the contracting party or user to provide said service” and their use does not require the user’s consent.

They are not used for additional purposes and are normally installed directly by the website owner or manager. They may be classified as follows:

  • browsing or session cookies: they ensure the normal website browsing experience and website use;
  • analytics cookies, similar to technical cookies when used directly by the website manager to collect information in aggregate form on the number of users and their browsing habits;
  • functionality cookies, which enable users to browse the website based on a set of selected criteria (for example their preferred language) in order to improve the service provided.

  1. Profiling cookies

Profiling cookies are aimed at creating user profiles and are used to send advertising messages in line with the preferences shown by the user during their navigation on the web. Web users must be adequately informed of the use of such cookies and must consent to such use.

  1. Third-party cookies

These enable the website to remember the user data throughout their visit (and for subsequent visits) enabling the user to browse the pages efficiently, interact with social networks, and use third party services.

Any browser may be set to accept all cookies, to reject them all or to receive a notice at the time of receipt. It is also possible to delete the cookies which have been stored on one’s computer. In the following websites it is possible to find information on the cookie settings of the most widespread browsers:

  • Mozilla Firefox

  • Google Chrome

  • Internet Explorer

  • Safari

  • Opera

De-activating some cookies may limit the website functions.

Most of the services provided through the Hitachi Rail website do not require the acceptance of cookies. However, blocking cookies completely may result in some services provided by Hitachi Rail becoming unavailable.

How Hitachi Rail uses cookies

Hitachi Rail uses cookies for the following reasons:

  • to track records of navigation sessions on its website in anonymous form;

  • to avoid that opinion surveys or pop-up windows, if any, are brought to the attention of the user more than once;

  • Hitachi Rail uses cookies for anonymous profiling; to gain information on the browser used (eg. Chrome), the country the user is in, and an anonymous user ID reference.

Amendments to this cookie notice

At Hitachi Rail's discretion, the contents of this document may be amended in future, for example in those cases in which should Hitachi Rail decide to add or remove options or characteristics of its own services and products, or should Hitachi Rail decide to rely on new content providers.
