seeing the thread Class 800 reminded me - and I had to check if it was about the Irish Class 800s, because, by coincidence, I met a woman by the name of Meabh last night, and i mentioned that there is an Irish steam locomotive named [Queen] Meabh.
(No, I wasn't trying to pick her up - but should anyone be tempted to use the line, I don't think it impressed her
)
But, having forgotten what little I knew about the class after seeing Meabh (or Maeve? - spellings seem to vary) in Belfast in 1970, I did look up the class on Wikipedia,
https://en.wikipedia.org/wiki/GSR_Class_800
to discover what I thought I knew was actually incorrect. (I thought the Queens had been used on Dublin-Belfast trains when, in fact, they were limited to Dublin - Cork.)
Wikipedia is helpful, but not terribly informative on what was arguably Ireland's premier steam loco design. Indeed, though it notes that modifications included a 'decrease in tractive effort' - it fails to explain why - a massive reduction in boiler pressure from 225 psi to 180 psi (presumably to reduce maintenance costs on the boiler).
It also fails to explain how a loco built by the Irish Free State railway ended up preserved in N Ireland - but perhaps railway enthusiasm transcends borders and territorial disputes.
These were nice looking locomotives - a bit like a cross between an A3 and pre-blinkered Royal Scot Wiki speaks about their haulage prowess in terms of clminbing out of Cork sans banker, but nothing about top speed - I suspect it was limited to about 75 mph - anyone know?
'tis a pity in many ways the 5'-3" Irish gauge prohibited the design ever having the chance to run on UK metals and allow the Irish Queens to strut their stuff.
