New factory
In 1904 the company opened a new factory at a site in East Pilton, Edinburgh, employing 3,000 at its peak in the 1950s. The works had its own internal railway system, which was electrified and used electric shunting locomotives built by Peebles themselves. This was the first electric line in Edinburgh (main line electrification did not reach Edinburgh until the early 1990s). In 1905 the company was exhibiting at the Third International Electric Tramway and Railway Exhibition. It also manufactured at least one (from an order of ten) electric locomotives for the Portmadoc, Beddgelert and South Snowdon Railway.
The business divided
In 1998 the business was split, with the Peebles Electrical Machine Division (Motors & Generators) being acquired by Pope (Australia) and the Transformer Division going to the Austrian company VA Tech.
Transformer division
In April 1999 a substantial fire destroyed the main transformer works in East Pilton. The company decided that a replacement factory should be relocated to Leith Docks to better facilitate transfer of the largest transformers onto ships for export. The Pilton site was sold for residential redevelopment. VA Tech closed the Leith factory during 2005 and continued service work only. The entire VA Tech company became part of Siemens that year.
Motors & Generators division
The motors & generators business relocated to Wood Road in the nearby Rosyth dockyard. Parsons Peebles Motor & Generators was acquired by Clyde Blowers Capital in January 2013. The company is still located in the Royal dockyard Rosyth and continues to manufacture and service specialised motors and generators.
