Hi I remember

The movie is a British film I think, certainly set in britain uk. 3 teenagers play truant from school 2 boys & 1 girl they go on a train to Wales. They all three are wearing there school uniform I believe. They spend the day in wales. I think I remember 1 of the boys ends up becoming the girls boyfriend but not definite about this. They then travel back home.

The movie is just a coming off age type movie (not horror or comedy). I watched this movie i reckon at least 20 years ago it is a colour movie NOT black and white

Many thanks in advance
