You've set a good puzzle here with your post of 22 March. Just to prove that I'm Irish, I'll try and identify them in reverse order!
The last photo of the five (J15 139) is definitely Kenmare, looking from the end of the line - the signal cabin at the far end with the little hut in front is the giveaway. It appears in a photo by the late Lance King with No.133.
The other photo of 139 is almost certainly at one of the stations on the Kenmare branch, but which one?
The third photo of an ex MGWR L(m?) Class 0-6-0 is NOT at Loughrea (which has a similar building), or Ballaghdareen, or Ballina, or Edenderry - all of which had very different station buildings - which, I think, leaves Ballinrobe?
So, find my copy of The Baronial Lines and Hey Presto - several photos which show that distinctive station building behind the train, which has just arrived from Claremorris. The small building on the right of the photo in the distance is the signal box.
Now, the photo of No.186 in 1968 - that was a puzzle as in those days I did every RPSI tour - but I didn't remember her going down the Cork line - which is where I thought this photo was taken. The answer is that this is the IRRS special, hauled by 186 on 29.9.68 when she ran Kingsbridge to Kilkenny.
Believe it or not, she was deputising for 184 which was still on CIE's books, and had been used in the making of Darlin' Lily that year, but simply was in no condition to pull a train! She had to wait for her full restoration for the making of The First Great Train Robbery before she could do that (and how!).
Can't help much further than that - I can't match the station building in the background with any station on the main line (the tour stopped at Sallins and Kildare), so it may be down the Carlow line? From Lance King's notebooks, I see that he took photos at Athy (not there), Mageney, Carlow, Muine Bheag, Gowran, on the way to Kilkenny; Milford and Carlow Beet siding on the return. I'm sure Mr Beaumont will have the answer!
Finally - the photo of No.161 certainly looks like Patrickswell - there's a photo of the restored station building on the Net and it looks exactly like the building in the photo.
Heavens - that's two hours gone - but an enjoyable bit of ferreting - I have six books open beside me now!
Great collection, Ernie - keep spending money buying them!
