Samuel Robert Douglas Power (1931 - 2021) was the CM&EE of the Western Region when I joined BR▸ Western Region as a CM&EE traction & rolling stock apprentice in 1975, his name is on the letter headed paper stating I had been accepted as an apprentice and to report to ......... etc
He over saw the introduction of the HSDT▸ (inter city 125) onto the Western.
Someone who made his mark on the railway but very few in the industry today will have heard of

I too have reason to be grateful to Mr Power (as we knew him) when he was CM&EE at Paddington. In 1973 he appointed me as an Engineering Assistant in his department based in the Departure Side offices at Paddington. He was very keen on training and career development, and he expected us to work hard and deliver what we were there to do. If something had gone wrong, we all dreaded the phone call from his secretary Anne asking us to pop down to see him.
He moved on to become CM&EE of the London Midland Region in Derby around 1980 I think. As ET says, he made his mark on the railway.
