The Contracting Authority is planning a successive overhaul of the engines of 25 train sets, each containing 2 engines, over the duration of approximately 24 months beginning in November 2012.

Each successive overhaul shall be completed in three weeks. Accordingly, please note that it will be a contractual requirement that deliveries take place successively as each train set is disassembled. A time plan will appear from the tender documents.

The Contracting Authority will itself perform disassembly and assembly of the engines, and is tendering a number of service and supply contracts necessary for the overhaul.

This contract notice covers the supply contracts; a parallel tender is being held for the service contracts.

The contracts/lots under this contract notice concerns:

— Purchase of new couplings between engine and transmission,

— Purchase of new A/C compressors.

A more detailed description of each supply contract can be found in Annex B.
