Beyer Peacock (Hymek)
1958 In order to cover the range of potential rail motive power technologies, Beyer, Peacock and Co formed a joint venture with Armstrong Siddeley Development Co Ltd, part of Hawker Siddeley, to manufacture diesel hydraulic locomotives; this was called Beyer Peacock (Hymek) Ltd[1].
1962 Beyer Peacock's partners were Bristol Siddeley Engines and J. Stone and Co (Deptford). They had delivered the first of 101 Type 3 diesel hydraulic locomotives on order for British Railways[2]
1963 British Railways was focussing on certain locomotive designs so the expected increase in orders was not going to happen. [3]
