Many of the floats had batteries in need of replacing but the depot budget didn't run to that, so this wagon was much in use. It was generally on the coldest mornings that the floats ran out of juice, and they had of course no form of heating whatsoever. Then, long before the days of mobile phones, you had to find a call box that hadn't been vandalised, only to find that you were 4th or 5th in the waiting list to get towed back. Oh, what fun it was.
Not even proper towing equipment, just any old bit of rope.
