So few people mention them. Glad I'm not the only one who does

And look what she changed her profile image to in the last 30 minutes or so, says a lot.
You're welcome.

Absolutely. You're comment about digging is just as relevant to this too!Indeed, but I only needed to quote one type to disprove the statement I was replying to.
If any good is to come out of this horrible incident is that the nationwide media coverage will hammer home the consequences of ignoring barriers.

I doubt it, sadly, these things always happen to 'others', they won't happen to 'me'.
+B is plus (half) barriers.
An example, and not my video.
The Mirror has comments about people saying the authorities were incompetent and clearly knew the problem so could have opened the line quicker, and one person even getting a dig in about privatisation?! Seriously?
Kate can at least be happy that some people supported her, which maybe gave her the confidence to unhide her profile and carry on. She seems quite proud of the fact she's upset some people and got her 15 minutes of fame.
Sorry to be so dumb, but I'm missing something here. How can it be an open crossing if it's got barriers?

I can't work out where she was going. I thought the incident is between Littlehampton and Horsham, yet she says her train was terminating at Horsham, *before* her destination, from which I infer she is southbound. However, she then says she has to go to Littlehampton, then Brighton, then Crawley, implying she's trying to go north.
Confused.
They where added at a later date & the two operate seperatley rather than as one. It was probably a more cost effective conversion.

Lincoln lost. Karma works in mysterious ways.She was going to the Crawley match.
Some people just do not know when to stop digging.
Oh I see. I think.
While on the surface AOCLs and ABCLs would seem very similar (to the lay-man the only difference you’d notice is the ‘B’ or lack thereof) - there are some differences in the circuitry and failure operation that I don’t know enough about to explain fully. While it makes little odds to drivers; maintenance staff still need to know difference hence why they weren’t just renamed ABCL.
AOCL+B was merely a 'conversion kit' to make a AOCL into a ABCL. The circuitry isn't EXACTLY the same as a brand new ABCL, although it is very similar, so engineers and project managers invented a new term to define the converted ones and distinguish them in future from bog standard ABCLs. Operationally there's no difference. AOCLs originally only had the flashing white light for the driver. By the time ABCLs came along, the flashing red light had also been introduced. The idea was originally to add the red to all of the locally monitored crossings whether open or barrierred, but the decision was also made to convert all the open ones to barriers as well. I think there's one AOCL left on the entire UK network. I don't know if there are any white light only crossings of either sort remaining.
The speed of the trains over the crossings will be determined by the traffic moment but should not exceed 56 mph at any time. There should not be more than two running lines. The carriageway on the approaches to the crossing should be sufficiently wide to enable vehicles to pass safely. The road layout, profile and traffic conditions should be such that road vehicles are not likely to ground or regularly to block back obstructing the railway.
I don’t get why they don’t get rid of railway wig-wags and use normal traffic lights. I bet a small proportion of drivers believe the wig-wags are just warnings rather than a legally enforceable light. Just put normal lights and a red light jumper camera up and I’m sure there’d be more respect.
