Those figures are very suspicious for a diesel-powered high speed train.
Maybe it's for a full train and one person in a car.

Many trains to Cornwall are pretty near full, so that's not a ludicrous
assumption. The one-person-per car, on the other hand, is less likely, as I
suspect that there are rather more family trips to Cornwall and rather fewer
single-businessperson-on-their-own-in-the-car than is typical of other
journeys.
