It could be controlled by a box of relays, I suppose, but it wouldn’t

Why does it need even that? A purely mechanical flush would work fine. Its
not as if the train is doing barrel rolls.


The vacuum flush saves water and retention tank capacity and allows the
train to run a whole day (or maybe two, for those which outstable) without
tanking;

How delightful. A mobile sewage farm.


The alternative is for the entire railway to be the sewage farm.

Why is fault reporting required?

So that Hitachi can be notified that there’s a problem and send a fitter
out; or at the very least see a pattern of recurring faults and investigate
the underlying fault, rather than just press the reset button every night.
(Whether these things actually happen is another matter!)

So the toilets are complex so that when a fault occurs due to their complexity
a technician can be notified? Calling Mr Heller....


Conventional toilets get blocked too. Conventional toilet door locks fail
too. Conventional toilets run out of water too...

On 800s the smaller toilets with the manual doors which therefore can’t
lock themselves out of use, generally get filled to the brim with ****
before people stop using them.

HSTs and 323s, however, I’ve seen clogged and blocked to the brim with
excrement and paper, which (a) stinks (b) is difficult to clean (for HSTs
it requires an extra shunt to the siding with the flushing apron and
application of hosepipe to either end of the pipe until it’s cleared; that
could be the difference between several sets leaving depot on time in the
morning or not).

Perhaps install more toilets in stations and get rid of them on trains
altogether. We're a small island, there are no journeys really long enough to
make them worthwhile except maybe the overnight sleeper to scotland but thats
not a commuter train.


People travelling 5h30 from Paddington to Penzance might disagree.
