I have noticed that at least in the last few years a lot more charter trains seem to have run from London Victoria or Paddington rather than Waterloo. I wonder why this is. More spare capacity at Victoria and Paddington than at Waterloo, maybe?
For example, Railway Touring Company and Steam Dreams tend to use Victoria rather than Waterloo as discussed in entry #6 of this thread on the pros and cons of different tour operators: https://www.railforums.co.uk/threads/pros-and-cons-of-different-railtours-operators.255978/ Steam Dreams trains have run out of Waterloo in the past but mostly seem to use Victoria these days if going anywhere on the Southern Region.
That said, Waterloo does still see the occasional charter train, either as a starting or terminating point or as an intermediate calling point (obviously involving a reversal en route).
