Alstom Prima is a family of modular diesel and electric locomotives. For the French market, the Prima has been delivered in electric version as SNCF BB 27000, BB 27300, and BB 37000, and in diesel version as BB 75000. One unit of an experimental quadruple voltage BB 47000 was built, but SNCF did not order the series.

As per SNCF new numbering adopted in 1999:
- Prefix "4" of the road number indicates assignment to freight service.
- Prefix "6" of the road number indicates assignment to Infra - Maintenance of Way

The BB 27000 is a series of 4-axle Bo'Bo'electric locomotives commissioned by the French state railway SNCF. Ordered in two batches in 1998 and 2002, they were delivered from November 2001 to February 2006. A total of 180 units have been produced. They have been designed for freight operations to renew the ageing CC 7000, CC 7100, BB 8100 and BB 12000.

Power output: 5,725 hp (4,200 kW)
Dual voltage: 25kV 50Hz AC / 1500V DC (2 pantographs)

The BB 37000 is a series of 4-axle Bo'Bo'electric locomotives commissioned by the French state railway SNCF. Ordered in 2002, they were delivered from April 2004 to December 2006. A total of 60 units have been produced. They have been designed for freight operations to renew notably the ageing BB 20200. This is the "international" version of the BB 27000, able to operate in Germany and Switzerland.

Power output: 5,725 hp (4,200 kW)
Triple voltage: 25kV 50Hz AC / 1500V DC / 15kV 16-⅔Hz AC (3 pantographs)

The BB 75000 is a series of 4-axle Bo'Bo'diesel-electric locomotives commissioned by the French state railway SNCF. Ordered in March 2004, they were delivered starting in November 2006.

This locomotive is the result of a collaboration between Alstom and Siemens. The internal electrical components are similar to those found in the Siemens 'EuroRunner' Rh.2016 made for ÖBB (Austrian federal railway), and the bodyshell, bogies and other equipment being of the Prima type made by Alstom, derived from the SNCF BB 27000.

Power output: 2,700 hp (2,000 kW) and 3,200 hp (2,400 kW)
