SNCB signed a framework contract with Alstom and Bombardier in December 2015 for up to 1362 M7s, with an initial order for 445 vehicles including 65 unpowered driving cars, 290 intermediate trailers and 90 powered driving cars.

A single Bombardier-built intermediate coach is currently at Velim, where traction is being provided by various electric locomotives, including one owned by VUZ.

The coach will go through the full testing and commissioning programme required to gain an Authorisation to Place in Service (APS), the legal permit required for commercial operation.
