No trolleys on trains and the Castle Cary shuttle bus is the rule if you're intending to travel by that means and you wouldnt be able to travel with a folded trolley if it's loaded with cans. Also I've seen many a trolley of this type fall victim to Glasto's rough terrain, broken and abandoned. They are not strong enough.
Lukas Nelson son of Willie is filling in for Nils atm & doing a brilliant job by all accounts. I think they’ll tour over here next summer but unlikely to be at the farm, we can live in hope though
