For information the Broadway shed is in the Caravan Clubs Broadway site, it has been converted inside to be one of the toilet blocks, it still has the internal platform which has a load of pictures of the old line, a bit like a mini museum, there is also a Scammell Scarab 3 wheeler parked in there.
Stayed on the site in our motorhome a few times, once at New Year and the wardens put on a party (bring your own beer) in the shed in the evening.
