Have been to the excellent Diesel Gala today and the new sound system is brilliant, clear and a decent but not over the top volume. I think we should supply details to the main line stations so they can catch up with us !!!
Don't make it too loud... I was in the garden at Stanway house a few weeks back, and the activity at Toddington a mile away was clearly audible. Lots of tooting and whistling, on an ordinary running day.
