I read that as built the Class 175s (and possibly 180s for that matter) were equipped with a "Boost" function which operated when Notch 4 was selected on the TBC.
I believe this has long been isolated, possibly before entering passenger service I'm not sure, but does anyone know how it would have worked, did the engines simply rev up more or was it something else?
