Doubtful if 186 will be back in traffic, there is no doubting that it is a fantastic loco , totally reliable and extremely popular with everybody but it is difficult to get realistic paths for it unlike 85 , 171 and 4 which were built as express locos .A case in point was 2012 May tour when it ran light engine from Ballybrophy 90 mins after the tour due to no path being available as it was underpowered to maintain the path provided.
