This may be of some use - a friend and I wrote it some time ago. I think the info we got for it was pretty much out of one source, the plaque on the side of 36!
No. 36 was built by Bury, Curtis, and Kennedy of Liverpool in 1848 for the Great Southern and Western Railway of Ireland, at a cost of £1995. Weighing what was at the time a relatively hefty 22t and 29cwt, and capable of 4,250lbs at 85% working pressure, it was regularly used on main line trains until its withdrawl in 1874, by which time it had accumulated 487,918 miles in service. It lost its small, four-wheel tender at this time. In Inchicore, enough foresight was used to see that, eventually, such an interesting and archaic lomocitve would be of interest in preservation for future generations - thusly, it was put into storage. In 1901, it was sent to the Cork Exhibition, after which, in 1925, it went to the Stockton and Darlington Centenary celebrations along with surviving coaches of a similar age - Dublin and Kingston 38, built in 1834, and D&K 48, built in 1838, and survives in the UFTM at Cultra. It was exhibited in Dublin for the bi-centenary of the RDS, before the three were put into storage in Inchicore dump. In 1950, the locomotive was restored to its former glory in a light green livery and was put on display in Cork station concourse. While coach No. 48 survived, unfortunately No. 38 was deemed too far gone to be saved and was thusly cut up.
In 2007, Cork station was refurbished - No. 36 was lifted into the new waiting area of the station, resplendant in GSWR pre-1875 dark green livery. It currently sits on the same type of bull-head rails it would have ran on in service.
