Your news item on the Essex lorry crash (NCE 4 July) concentrated on progress, or lack of it, on risk assessment of road over rail bridges: such assessments having being recommended by the Health & Safety Executive following the Selby disaster.
It is clear from your report that the bridge performed more than adequately. The 'high containment' parapets functioned as designed and prevented the lorry from falling onto the tracks below.
The performance of the bridge was not matched by the performance of the road vehicle, the cab appears to have sheared off from the chassis and fallen onto the line!
I suggest that the risk assessments of road over rail bridges ought to consider the crash worthiness of road vehicles likely to use a bridge so that suitable mitigation measures can be adopted.
