The challenges relate to financing, to technical and regulatory alignments (agreeing on the gauge width of a cross-border railway network, for instance, or on national axis-load regulations), and to matters of governance and even human relations. It is obviously very tricky to coordinate a program’s responsibilities and processes across several countries when there is a great diversity of languages, cultures, financial capacities, and political and regulatory environments. Matters are further compounded by national self-interest, as in staffing, and sometimes by a legacy of historical rivalry and mistrust.
The challenges can be overcome, however, through the skillful deployment of established best practices during the program's various phases.
