I'm struggling to grasp why BR switched to flat fronted cabs, given that locos with noses seemed to fare much better in accidents. If you compare something like the Lunan Bay (1975) and Glasgow (1977) accidents - both class 40s - with something like Crewe (1980) or Micheldever (1985), a 47 or a 33 seems a bit of a death trap in terms of the damage sustained. Not to mention the great big whack that DP2 took in 1967, already mentioned.
Was the additional visibility really worth the much higher risk of the cab being crushed and its occupants killed?
