The following list of Intended Invitations to Tender (IITT) include the actions that are funded and approved for initiation on ESA programmes for the Space4Rail Initiative.

For each listed IITT, a summary note of the intended action will be found (short description of the work to be carried out, estimated price range, planned publication (quarter), etc.).

Any company interested in participating in an IITT listed activity can declare its interest in ESA-STAR Publication.

The expression of interest can be made public or shared with ESA and National Delegates only. Entities can indicate whether they would like to act as a Prime, Subcontractor or either of these roles.  When made public, all users accessing ESA-STAR Publication will be able to see the expression of interest, the choice of rile, contact details as well as a link to entity's esa-match profile page. This feature allows a proactive search for industrial partnerships and is a valuable tool for SMEs to make themselves known. In addition, entities are invited to launch an esa-match marketspace ads to look for partners and collaborators, Ads can be linked to specific tender actions. More information about expressions of interest can be found here.

The Global List of IITTs defining the ESA procurement programme for the year is issued by the Agency on ESA-STAR at the beginning of the year and is updated at least once a month. Potential suppliers are invited to regularly consult this list.
