There was an absolute whopper at Waterloo, presumably dating from Southern Railway days, many columns wide and with plenty of depth to get all the stops in one column (modern video screen system designers please take note). Even the wood was kept nicely polished. It probably had its own full time operator round the back.the old wooden departure boards on platforms at big stations before PIS came in. They may have changed to plastic towards the end, but you could read them as clear as day.
It was stripped out in a 1970s remodelling, replaced by a Solari board. Bizarrely, I saw the contractor on the project advertised the redundant board for sale in the Railway Magazine.
In 1980, in Los Angeles, California, I went to a restaurant near Universal Studios called Victoria Station http://www.oldlarestaurants.com/victoria-station/ . Apart from having part of the dining area in about four old Mk 1 SOs, in blue/grey livery,which were visible as you approached, on entering there, in all its splendour, was the old Waterloo departure board. All sorts of nonsense station combinations showing, of course. The themed restaurant moved on after some years, the Mk 1s were probably scrapped, I wonder what happened to the wooden departure board, so far from home.
