You have the skills Patrick - just haven’t tried them! Talking of PPs, here is a painting of one pre-WW1 on the Greenore boat train. In those days the fastest way to reach London from Belfast. The original was commissioned by Sir John Harcourt, Lord Mayor of Belfast, c1957, and hung in the BR boardroom at Euston for many years. Sir John had used the train many times and had great affection for it: the border sadly killed it off. The painting was by Raymond Piper, more famous for orchid paintings. Piper travelled extensively around the network to track down every vehicle used on the train and sketch it. The PP - by 1957 black with a riveted smokebox - was captured at Newry shed, and the sketch survives.
