Hi all,
Just a question I had long pondered and never really had a definitive answer to; why was there a special pool of 67s for WHL workings, and why did/do they require block/tread brakes (and the 80mph speed restriction)?
Seems a tad peculiar as I'm sure other disk braked trains use the route - thinking specifically, though please correct me if I'm wrong, of class 66s, 73s and 43s and, of course, the mk5s.
So, was this restriction as a result of a special local instruction or is just something traction specific? I can't imagine there's a world of difference in terms of the gradients, leaf fall etc to that experienced on the HML - just seems like a rather curious requirement.
