Although, for the record, my ticket was checked a total of 0 times on the train, I just had to wave it at barrier staff but I could have potentially got through the barriers on a travelcard and travelled on it :P
The doors only opened at the stations where we stopped for a break - but the train did have to stop at stations a few times, which confused people who tried to board it... and then it sailed off again, leaving them bemused and fellow passengers in the train pointing and laughing at the unlucky fellows!
