Were 158s the last .uk passenger stock to have non-retention toilets?
They're all over 20 years old now.

Probably. Of course retro-fitting of tanks has proved to be perfectly
possible on 158s, so it's a question of who funds it (and the necessary
depot work.)

Meanwhile back at South Tottenham - the OPs problem station - once the 150s
are no longer in use there shouldn't be a problem?
