The CP 2240-class is an electric multiple unit used by the national train operator Comboios de Portugal. Each EMU features 3 cars, with the ends being driving trailers, and the middle being a power car (which houses the traction motors).^[1]

The units were assembled between 2003 and 2005,^[1] by Alstom, reusing the old Sorefame body shells belonging to the 2100, 2150 and 2200-class EMU's, to keep cost down and avoid fully scrapping old rolling stock. The bogies were custom-built with new Alstom traction motors,^[2] and are in the 1668mm Iberian gauge.

They are able to operate in multiple configuration with up to 3 units, for a total of 9 passenger cars.^[1]
