    Yes I am an active volunteer
    Just to confuse things, chocks are referred to as 'TRIGS' at www.TrolleyMuseum.org
    The origin is not known but may refer to the trigonometry required to calculate a triangle with a curved hypotenuse.

    If it's any help for those making their own, I'd suggest:
    A softer wood rather than a harder one - it's generally preferable to crush rather than ride up on.
    Cut the curve as close as possible to the wheel radius - too shallow & the wheel will climb.
    Don't paint the base - maximum friction is needed on the railhead.
    We release the brakes & confirm that the car is secure.

    The only Scotch we have around here is imported in bottles.......
