It was not only steam at the AJECTA-centenary in Longueville. Each 3rd full weekend of September AJECTA organises the Longueville open days -that always attract lots of Frenchmen, Dutchmen, Britons and other steam train fans. SNCF museum diesel loco 72084 -restored in it's original colours- shuttled four times with a freight train on 18 September 2011, passing through Longueville. The second passage saw it pushing/banking, since the train was pulled by a steam loco that I tried to photograph. Much to my chagrin, the photo flopped ignominously, so only the 72084 could be taken on. The third passage I missed completely.
