there's nothing in the national rail conditions of carriage or train company's t&cs that stop me from doing this, so far as i can tell. i use it twice daily for almost two years now. a hundred meters walking and you are on promenade riva and in the harbor. second 'must grow' for next year. it was hard to determine exactly what changed, but just that something did. okay with just what is already there? and i find walking so relaxing and refreshing...not just from an exercise and fitness standpoint, but mentally. except meanwhile they're a lay state.
