Didn't FGW try and fit a timer delay to HST toilets to prevent them from being flushed in stations??
I recall seeing this only once on a HST set running BRI - PAD. But that was some time ago and i've not seen one since...!
I had another toilet incident on a SWT service to Waterloo last Saturday, all the toilets on a 3 car 159 were LOOU...

As we still had another 45 mins left of the journey, I sought out the Guard and explained that I needed to use a loo as a matter of urgency, and that waiting till arrival into Waterloo was not an option. He opened what was supposively the cleanest toilet for me to use under my own peril... Put it this way, I'm glad I hadn't already eaten my lunch
