I dont get the connection? Video is of a North American level crossing and not a curve in sight??

Leaving Brian's comment to one side , The time delay between the gates closing and the train crossing in the video is very short compared to my experience of UK crossings. We have one in Downham Market where I live and the gates can shut a full five minutes before the train arrives.

It was a bit close but the barrier for road traffic going right to left was a long way back it seems from the track. I think the barrier for traffic L to R gives an unhelpful perspective with that camera angle. Still can’t see any R1 curves though. R-

Even using the 360deg camera I can't see where R1 curves come in. The camera bends the vision a little, but not enough to be R1.

OP has inserted the wrong link.

Apologize. I tried to log in this morning to explain but I couldn't as the internet was on a go-slow.
When I view the short film on my tablet, the 360 degree camera view makes it look like the train goes round an incredibly sharp curve. Obviously this is jot the case with other internet devices as you lot would have seen it and had a chuckle. Is only a bit of humour.
