The 2-axle coalfish and bass wagons from the civil engineers fleet are gradually being disposed of, as a result of new Wascosa wagon deliveries -

First wagon in the train is OBA 110156 with mesh doors (most OBAs have
wooden doors). The same wagon is pictured here -

Second wagon is OCA 112300 - the thumbnail at the top right of this LTSV profile shows the same wagon as it looked when freshly painted in Railfreight red back in 1989 -

Those two are "bass" wagons used for general engineers materials (sleepers, scrap rail e.t.c)
The other 13 wagons are MFA / MHA / MPA "coalfish" mainly used for ballast and spoil. MFAs were formerly MEAs and before that HEAs (profile here -

These 6Z83 workings to Attercliffe have been running occasionally during 2022 and 2023, from either Toton or Doncaster. For example in June there was a 6Z83 from Doncaster on the 7th, and two from Toton on 21st and 29th (which is pictured here -

Most of the coalfish and bass wagons seem to end up at Attercliffe, although a few have been sent to Kingsbury from Bescot. From what I can tell, the coalfish and bass fleet have now largely been removed from service but there are still a lot of them in sidings waiting to be sent for scrap.
