A few crossings I can think of:
A403 St. Andrews Road, Avonmouth, Bristol: has lights but no barriers. Interestingly, on the Docks side of that crossing the signals - SA41 and SA43, shown in the photo here - are still present despite the line having been out of use for some time and, on the Docks side of the crossing, badly overgrown. It would also appear that they have never been turned off as shown in the closeup of SA41:
The land on the southern side of this crossing, down toward Kingsweston Lane, has no track in situ and a building has been errected to house what is, I understand, the largest wine warehouse in Europe. Laughably the arrangements were changed in 2010/11 by which deliveries of wine now arrive into a siding near Parson Street Junction by train and are then taken to the warehouse by lorry. Surely with all the signals and most of the track in situ - there are three signals still present in all - it would have made more sense to reinstate the line over the A403??
Kingsweston Lane, Avonmouth, Bristol is where the line that also crosses the nearby A403 crosses Kingsweston Lane. On the southerrn side of this crossing the track is, I think, still in place. Between Kingsweston Lane and the A403 the track has been lifted and an embankment now covers where it once ran.
Abergarw Road, Brynmenyn has an LC on the disused Tondu - Pontcymer route. Rails also in road plus gates and some lights. There is, I think, another LC on the same line up at
Llangeinor not far off the A4064 where the road signals and gates are gone but, on Google Earth, the lights that would have confirmed full function of the LC to the driver are still in place. Up towards Pontcymer the track appears to be clear but I believe there is a preservation project up there.
