My European Rail ticket from Berlin arrives at Mannheim HBF at 13H28 on train 871, and I have to change trains, from train 871, to train 9554 (Paris EST) leaving at 13H41, just 13 minutes to change trains. Is this possible without having to run for the train? Is the inbound train platform at least beside the Paris EST train 9554. It doesn't seem very much time to achieve this change. Please advise.
