General manager and engineer of the Rhymney Railway Cornelius Lundie (1815–1908). For over 40 years, he was, a few years prior to his death, appointed consulting director to the Company, and actively discharged the duties of that office until the very end. As an engineer he designed and constructed many extensions of the system and widenings of the main line, including a double-way tunnel under the Cefn On or Caerphilly mountain, and a masonry viaduct of seven spans over the River Taff, besides new locomotive shops at Caerphilly, and other works. He was 93 when he passed in 1908 and is thought to be the oldest railway director of his time.
