The Whitehead (mk2) set has a ex-BR half brake (463)fitted with a genny, they also have an ex-IÉ 'Dutch' genny van No.462 (IÉ No.3158).
In Dublin a the RPSI have a set of Cravens, with two BR mk1 genny vans, 3185 in Inchicore and 3173 under overhaul at Mullingar. (As an aside the Cravens are probably more contemporary with mk2 stock than mk1s, both being early 1960s designs, although Ireland wouldn't get mk2s until the early 70s).
I'd agree that much of the IÉ mk2 fleet was beaten down by the mid-2000s, corrosion being a problem but this didn't affect the aluminium bodied Cravens - these were withdrawn in 2006, while the mk2ds, despite being 10 years younger, were finished off in 2008.
I miss the mk2s, particularly on my local Rosslare line, but am glad Cravens were saved as they are a unique Irish design, there will always be rakes (literally) of mk2s and mk3s in the UK.
