Im curious, have all the half gates on level crossings been replaced? That always struck me as an open invitation for some munter to drive round them.
I doubt it.

I don't remember all these accidents when level crossings had big and heavy white gates operated from an adjoining signal box by a signalman turning a great big wheel...
I dont think I have ever seen a half-gated level crossing :?......Im curious, have all the half gates on level crossings been replaced? That always struck me as an open invitation for some munter to drive round them.
I'm getting my information from the RSSB report into the Ufton accident. Contained with in is a reproduction of a flow chart to determine what type of level crossing is appropriate in various different situations this is taken from Network Rail Code of Practice RT/E/C/11600 - Signalling & Operations Telecommunications - Page X18. The flow I'm following says START - Permitted Speed >200km/h -YES- Level Crossing Not Permitted.
Ah - but you don't have a permitted speed 'greater than' 200 km/h, (125 mph) so you follow the other branch.
Ah - but you don't have a permitted speed 'greater than' 200 km/h, (125 mph) so you follow the other branch. When you come to the decision 'is line speed greater than 160 km/h' (100 mph) - you then find you need a manually controlled barrier. AFAICT that's still the current situation.
It would be a different decision if the first question was 'greater than or equal to' 200 km/h - but that would be a different symbol.
To be fair that's not really a good comparison, there was also less road traffic then too.

Also, it was quite common for there to be separate pedestrian gates which were locked in the shut position by a lever in the adjoining 'box. This prevented silly girls with push chairs rushing across in front of on-coming trains.
The picture is of a half-barriered crosing. Is that what you mean ?
If so then the answer is no. It is not permitted to fully enclose the road at an automatic level crossing so as to remove the risk of a vehicle or animal/person, etc becoming trapped after the lowering sequence has started. The rules are that the exit must be unobstructed.
This applies to level crossings of this type world-wide.
Unfortunately this does mean that a road vehicle driver, or anyone else for that matter can enter onto the crossing after the lowering sequence has commenced. This is uncontrollable and relies on the self dicipline of the crossing user.
Where there are full width barriers (as opposed to gates) then the barriers must be supervised at the time of closing either by sight or by CCTV.
Where a road is lightly used or the crossing is on a private access road, then a full-width barrier can be provided but it must remain closed and be operated on each occasion someone wants to cross the line. Usually these are hydraulically operated with a slow-release mechanism that allows the barrier to gently lower after a short period of time.
