Hi Steve, are you sure thus is an older commuter train and a newer aticulated Talgo type? I see a BB 22200 with ex-Corail passenger cars on a long distance train and a TGV, either a Sud-Est or a RĂ©seau series. TGVs are articulated indeed, but the system has nothing to do with Talgo. The "anneau d'intercirculation" is a key feature of the TGV technology and was entirely developped by Alstom.
