Chettisham barrier indicator.

A few tweaks as regards timings etc but by and large finished. It's worth skipping half the video as not a lot happens. Third Drove is first to operate, Second Drove is er um second, followed by Black Bank then North Fen and lastly Beald Drove.

 

I was always fascinated by this when it was in the box. I wish i'd spent some time videoing it.
