By chance I went across this crossing about an hour before you did. There was the most terrific thunderstorm and extremely heavy rain. I wouldn't be surprised if the OD lenses got dirty from splash back (ie big raindrops bouncing back off the road).
As others have said there's no CCTV; that's the whole point. And whilst some people might not like them, the people I spoke to in the safety regulators are convinced they are safer than MCB crossings (CCTV or otherwise), as well as being cheaper to operate.
They may be. That's still no comfort to the staff and passengers afflicted by the them.
The equipment failures on the Joint and Ely - Norwich lines regularly stop the job. Aslockton and Orston Lane also seem to be new problem children on the Nottingham - Grantham line.
Then there's the operational timings that have no flexibility to suit different circumstances. The Bottesford platform starter now sits and waits for Normanton AHB to operate so late or not, you sit on a red for up to a minute. You then get a yellow and have to crawl around to the poorly sighted signal at the former Bottesford West Junction while Orston Lane MCB-OD operates. If you're late, now it's all automated, forget trying to make up time.
The public were told 'it's great, the barriers will be down for less time, and will be able to raise more often between trains'. Oh wait, no, Blankney and Aslockton crossings are both the only access between platforms at Metheringham and Aslockton stations. The way it's set up for sequential trains at both stations, it doesn't take much of a delay to the service to have multiple trains hit the strike in points and keep the barriers down for 10-15 minutes, meaning you get to the station in plenty of time and physically can't get to your train and miss it because you're on the far side and it's the middle of 3 trains.
Bingham is the same - trains are booked a minutes wait, so the crossing doesn't come down and the signal doesn't clear. In the day time if you're late that means waiting. If you're early, which anything that runs via the Allington Curve from Sleaford is, up to 5 or 6 minutes, the barriers come down after 1 minute and block the road for 5. The bodged solution to that is now to hold the train at Allington West Junction in the dark on the curve until it's nearly late and hope it doesn't make time en route.
The tail wagged the dog and we now have a rubbish automated solution that is a) generally unreliable and b) doesn't do what we were told it would, except get rid of the person in the shed that knew when to drop their barriers for different circumstances.
