To be honest, I noticed the lack of tubes, but just assumed that they had taken advantage of the later change (mid-1890s) in BOT regulations and removed them. The first two Castlederg Kitsons (1884) had condensers, but the third, which was the locomotive version of a six window heavy class (1890?) did not because the BOT no longer required them. Sorry, but due to the Skebawn and Castleknox project I have acquired more knowledge than I ever needed of Tramway regulations.Peter Butler wrote: ↑Sun Jan 14, 2018 6:26 pm I decided to cheat at the time by excluding the all important condensing tubes on the roof and have now realised what a silly mistake that was. You were all too polite to tell me how wrong I was. In order to correct the error and complete the job I knuckled down yesterday to construct a suitable add-on system to attach permanently to the roof and improve the overall appearance. It now looks more like a steam tram.... including the advertising from our sponsor....
