In watching cabride videos from all over the world I note that most RR's employ full four quadrant gate systems to protect their engineer / drivers from road vehicles that run around the half assed gates used in the United States.
Operation Safety be dammed. The effing railroads are NOT interested in safety, only in company profits. And a PR campaign with pretty logo's and safety 'classes' are a lot cheaper than installing the proper protection at grade crossings.
And just how much is a human life worth? Twenty percent higher cost for full quadrant gates is not that much of a cost protecting train crews AND the public idiots who seem to enjoy putting lives at risk.
