E London line could encourage Horniman to run more events, which, if they are manageable, could be a good thing. However, over-excitement about the potential of the line could also lead to more activity than the local community had bargained for.
I hadnt even concidered this - and it just adds to my concern. It's not just about driving to the Hornimans and the number of cars - it's also about the shere numbers that Horniman Gardens can sustain.
