China Railway Rolling Stock Corp has submitted a proposal to make a significant investment in national rail operator BDZ Holding, caretaker Minister of Transport, Information Technology & Communications Hristo Alexiev has announced.

There are three elements to the CRRC proposal:
- Chinese refinancing €130m of BDZ Holding’s debt; in February the minister said an existing loan had an undesirable interest rate of 8%.
- Supplying new diesel and electric multiple-units worth €170m. These would conform with national and European standards, and be delivered ‘promptly’ to help meet BDZ’s urgent requirement for working rolling stock;
- Chinese investment in a new factory for the assembly of multiple-units in Bulgaria.
