We are sad to report that during last weekend ballast was removed from underneath the Miniature Railway track making two sections of track unsafe and putting the Mini Railway out of commission. The Railway people are doing their best to source replacement ballast so that they can make a repair but are worried that this will stop them running the Railway for the rest of the summer.
See the FB page for Brockwell Park Miniature Railway for more details.

So it was Sunfall Festival that was responsible for Mini rail damage. Please throw the book at them!
Our most recent information is that this was not down to Sunfall and it remains a mystery!
