Sorry, no etymologies found.
Soon the coroner, Michael Baker QC, will be helping the jury understand the "flangeway gap", which is what a train needs at junctions if its direction isn't to be fatally confused.
A bit of background for you, the flangeway gaps on the crossing are around 4 inches wide, his caster wheel is anywhere between 3 to 8 inches.
If he wasn't going fast enough (uphill at age 69) his caster would’ve more likely fallen into the flangeway and he would’ve been stuck regardless of whether the crossing was working or not.
