is it correct to say I travel on train or by train
Most native speakers would tend to say they travel " on the train".You can say 'get on a train', but you definitely say 'travel by train'.
I can only reply as a native speaker, but I can assure you that "I travel on the train" is more common usage than "....by train".:shock: I did not know that.
But is it also grammatically acceptable? I mean, if the native speakers use it, do the native philologists also use it? Because so far I have been teaching my students the 'by train' version. Could I actually tell them it's OK to use travel on train?:-|
