I last saw class 84s in a scrapyard at Hyde near Manchester. About 1980. They must have arrived by road as there was no rail connection. They looked to have just been dropped onto a pile of scrap, not placed neatly on the ground. Some of their innards were scattered around. I gather they had come from Metro-Vicks,AEI in Trafford Park. I cannot say if they were the worst thing on rails or not. Speaking of M-V, I recall seeing a class28 at Guide Bridge in the dark. Accelerating away from a signal with a very irregular engine sound and sparks from the exhaust,spectacular even if it was the worst.Perhaps more poignant at an earlier time was seeing a clapped out J39 or some such wheezing its slow way to Gorton for scrapping. She had 3 or 4 dead locos in tow with their smokebox doors open and con rods removed.Had some good runs behind 84,s in the 70's
