IT IS IMPOSSIBLE TO LOSE A TRAIN...OR AT LEAST VERY DIFFICULT

SPANGLISH WARNING: IT IS IMPOSSIBLE TO LOSE A TRAIN

Many Spanish people use the sentence: "Sorry I am late, I lost the train". This sentence makes no sense in English because if you lose something it has to be small.

So for example you can "lose your keys" or "lose your bag" but a train is a bit big to lose. Instead you need to use the verb "miss". So the correct sentence would be "Sorry I am late, I missed the train".

Hope that helps!
