I read recentl that the class 40 locos were withdrawn earlier than expected as their brake power was actally less effecient than a class 37. This meant that the 40's, although more powerful than the 37's, and being able to haul longer/heavier freights, were unable to efficiently stop a freight, taking ito consideration their own weight; it was therefore more suitable for 37's to haull shorter trains knowing that they could brake when required, being somewhat lighter than the 40's.
