201, 202, 203, 204, 205, 210, 211, 212, 213, 214, 224 and 230 are the mothballed 201s as of now. The orange 201s (201-205 and 210-214) aka the non-push/pull 201s were withdrawn around 2009, with 214 "River Brosna" being the last non-push/pull 201 to come out of service in July of that year.
230 "River Bandon" caught fire on the 6th of June 2013 while it was hauling an Enterprise set. It was put into storage shortly afterwards and hasn't seen any usage, though in July 2017 it got partially rebuilt using 211 "River Suck" as the donor (apparently), but nothing of it has been done since.
224 "River Feale" was stopped and stored after a structural failure had happened while hauling the 14:25 hr Cork Kent to Dublin Heuston service. It experienced a coolant leak and electrical fault that caused the locomotive to shut down while approaching Limerick Junction and its midsection began to sag downwards. 224 was deemed a failure and towed to Inchicore, where it currently remains. The RAIU report concluded that an unnecessary weld repair was applied to a structural chassis plate, which in turn resulted in the underframe eventually failing.
225 "River Deel" was stored in September of 2010 after having a fatal collision with a tractor in Roscommon while hauling a container train on the 09:30 hrs freight service from Ballina to North Wall. Fortunately, 225 was overhauled and reinstated, Returning to freight service on the 24th of October 2019 and passenger service on the 8th of November 2019.
