VLocity is the right name for the things
 

OH OH,
Smashing the grand old level crossing gates at Ballarat in our Mexico.
A rampant Vline VLocity set unable to stop.
Mention of the WHEEL SLIDE detector does make me muse about our NSW Tangarbage sets.
Our Tangarbages are renown for not stopping when that wheel slide sensor goes off.
No sand on our Tangarbages.
Not permitted.
Thumping the spring parker brake button is about the only recourse on a Tangarbage when that wheel slide goes off.
One wonders how many other things suffer this drama in wet weather.

Glad it didn't derail and there weren't any vehicles on the crossing!
