Nord 4.001 to 4.075 and 4.636 to 4.990, commonly referred to as 180 unités, were freight steam locomotives developed by the Chemins de Fer du Nord.

Construction history

These locomotives were built in several series by different manufacturers. Beginning in 1879, models incorporated a Belpaire firebox, and from 1890 onward, driver cabs were introduced.

In a comprehensive renumbering effort during 1921, the remaining units were assigned updated number sequences to enhance fleet organization:

• Earlier series’ numbering was consolidated and adjusted in accordance with locomotive retirements and active status.

This production overview demonstrates the company's approach of engaging multiple established builders to fulfill growing demand while progressively incorporating improvements such as the Belpaire firebox and enclosed cabs to boost operational performance and crew safety over time.
