Railnews - Rolling stock leasing company Porterbrook is buying 49 per cent of Scottish railway firm Brodie Engineering, based in Kilmarnock. Porterbook said Brodie is the only active rail engineering business in Scotland, specialising in heavy maintenance, refurbishment and overhauls. The Caledonia Works were previously occupied by Wabtec and before that Brush-Barclay, the successor to Hunslet-Barclay. Porterbrook CEO Mary Grant said: A healthy supply chain is fundamental to a reliable and efficient railway.
