@wills_trainspotting: Eurostar 373209 + 373210 race their way past Boxley valley working 9031 13:12 Paris Gare du Nord to St Pancras International. This is the first e300 to be fitted with ETCS and the first time they've been out in passenger service in just over 3 years. #trainspotting #highspeedtrain #fyp #eurostar #highspeedrail #tgv #class373 #paris
