The V/Line VLocity is a diesel multiple unit train built by Bombardier Transportation, Dandenong for V/Line. In November 2001 National Express signed a contract with Bombardier Transportation for 29 two-carriage diesel multiple units. This was later extended to 38. The design was an evolution of the Xplorer/Endeavour railcars. Original plans were for the 29 sets to be fitted with 2+3 seating for a total capacity of 173 passengers per two-carriage set, but in February 2003 this was changed to 144 seats in a 2+2 formation.
