Iris 320 is a modified TGV train operated by SNCF International as a dedicated track recording train for high-speed railways.[1] The train can run at 320 kilometres per hour (199 mph) and consists of two power cars and eight trailer coaches, providing a 160-metre (524 ft 11 in) long laboratory.[1] It was converted from former SNCF TGV Réseau passenger train number 4530.

The train is primarily used for monitoring the whole of the French high-speed LGV network every 15 days.[2] In addition it surveys other main lines in France operating at above 160 km/h (99 mph)[2] and the HSL 1 high-speed line in Belgium for Infrabel.

Once every two months, Iris 320 takes a survey of the Channel Tunnel for Eurotunnel (since December 2010) and of High Speed 1 for Network Rail (Channel Tunnel Rail Link) in the United Kingdom (since 4/5 May 2011).[3] The cross-channel trips are diesel-hauled by Eurotunnel Class 0001 locomotives and travel at 100 km/h (62 mph).[4][5]
