Farewell programme
We can probably thank the late Gerry Fiennes for the purchase of the Deltics, or as he put it "the policy of building diesels of around 2000hp lies in ruins around us, nothing less than well over 3000hp under the bonnet will do". Certainly the various Type 4 designs were not really any great advance in on-rail performance over a Pacific in reasonable shape, at the time the Deltic was the only locomotive which could advance on this, a machine that could reach and maintain 100mph (and more in reality) where the rest could only struggle to 90mph or less. We will certainly never see anything like them again.
