Just another idle thought, but does anyone know how much a new mainline diesel would cost?
I'm sure it is complicated as the larger the batch sold, the cheaper the individual cost. Maybe a "£xx million deal for 30 locomotives" might also include a set of spares like new diesel power packs, (or free 500,000 mile servicing

)
But generally are we talking a £1m for a Class 66, or £2m, or what?
