I realise that there will not be a definitive answer for this, but does anyone have a rough idea about how many miles a 'typical' mainline engine will have covered before it is withdrawn.
I'm thinking of (say) an 87 that spent its time going from Scotland to England all day, a Deltic that ran for years and years or a 37 that has been around since Noah was a lad.
Just curious
