Andrew Barclay Sons & Co.

Andrew Barclay Sons & Co., currently operating as Brodie Engineering, is a railway engineering company, specializing in the heavy maintenance, refurbishment and overhauls for both passenger and freight rolling stock. Based around its works at Kilmarnock, it is the only active rail engineering business in Scotland.

The company's history can be traced back to the establishment of an engineering workshop in Kilmarnock in 1840 by Andrew Barclay. It produced numerous steam locomotives during the nineteenth century and, during the following century, it produced several fireless and diesel locomotives as well. Ownership of the company has been exchanged several times, having become a private limited company in 1892. It was acquired by the Hunslet Group during 1972, after which it was renamed Hunslet-Barclay.

During the twenty-first century, the business has changed hands multiple times, having been purchased by LH Group in December 2003, then becoming part of the FKI Group under the name Brush-Barclay during 2007. Four years later, both Brush Traction and Brush-Barclay were acquired by the multinational railway engineering company Wabtec. During July 2020, the Kilmarnock works was acquired and reopened by Brodie Engineering Ltd after Wabtec had opted to close down the site. In early 2024, Porterbrook took a stake in the business.
