Yes, the Dulwich Estate started to regenerate after the coming of the railways. Prior to that both Dulwich (and then then not named) East Dulwich did market gardening and dairy for the Metropolis. On "The Dulwich Experiment"; it came as a surprise that the LCC bought 90% of the Dulwich College places for scholarships. At current prices of annual fees >?12k this was a major expenditure. It does explain why, in the 1950s and 1960s, quite a few East Dulwich boys from lowly families attended Dulwich College.
