Warship diesel-hydraulic 821 "Greyhound" seen here at the 1991 Old Oak Common open day
<b>What a lovely sight!</b>
British Railways Class 42 Warship D821 'Greyhound' basks in the sunshine, flanked by fellow diesel hydraulics Class 35 Hymek D7018 in two-tone green livery, and Class 52 Western D1015 'Western Champion' (decked out in the experimental 'golden ochre' livery that she carried in the early 60s). Beautiful sunshine and beautiful locos :)

The <b>British Rail Class 42/43 Warship</b> diesel-hydraulic locomotives were introduced in 1958. It was apparent at that time that the largest centre of expertise on diesel-hydraulic locomotives was in West Germany. The Western Region of British Railways negotiated a licence with German manufacturers to scale down the German Federal Railway's &quot;V200&quot; design to suit the smaller loading gauge of the British network, and to allow British manufacturers to construct the new locomotives. The resultant design bears a close resemblance, both cosmetically and in the engineering employed, to the original V200 design. 

Warship locomotives were divided into two batches: those built at BR's Swindon works were numbered in the series D800-D832 and D866-D870, had a maximum tractive effort of 52,400 pounds-force and eventually became British Rail Class 42. Thirty-three others, D833–D865, were constructed by the North British Locomotive Company and became British Railways Class 43. 

The locomotives were allocated to Bristol Bath Road, Plymouth Laira, Newton Abbot and Old Oak Common sheds.

Two Class 42s are preserved, D821 and D832. More info here: <a href="https://en.wikipedia.org/wiki/British_Rail_Class_42" rel="noreferrer nofollow">en.wikipedia.org/wiki/British_Rail_Class_42</a>
