Abtus Voidmeter

Hi guys,

Were these voidmeters ever used on Irish railways?

What IS it? What does it do?

Personally, I've never even heard of it.....

Used by PW to detect a 'void' under the rail in need of ballast, amount depending on the amount of deflection of the needle as the traffic passes over the rail. Would have no use now with such heavily ballasted track and more modern electronic assessment of rail/ballast integrity I would think.

And there was me thinking that "Abtus Voidneter" was a nasty character out of a Harry Potter novel........

Well it's a Void Meter of course (slight typo in the post)
