Hissing Pendolinos?
Hi all,
Only my 2nd post - so i beg forgiveness if this has been covered many times (i couldn't see any reference to 'hissing pendolino' in the search), is in the wrong place or is just a plain silly question!
When travelling on the London - M'cr Pendolino, usually in the quiet coach, occasionally there's a weird hissing sound emanating from the corner where the WC is. It kind of goes 'Tsssstss tsssstss tssstss' pause, and then may or may repeat itself. It sounds like it could be some kind of air-freshener, but doesn't seem to correspondend to the WC being used, and i can't smell any 'pine freshness' in the air.
And it's really bugging me! Anyone know what it is?
Cheers all!
Dog.
