    Interestingly I looked up the section on brakes in the Black Book. The text refers to a "vacuum pump" and there is a figure caption to a drawing in which the caption is labelled "vacuum pump" (agreeing with the text) but in which the component in...

    So is it a vacuum pump, or is it an air pump? Is it a railway station or is it a train station? In both situations we all know what people are talking about and as far as I can see both terms are correct in their respective situations. On the...

    Not a day for any exhaust, but a couple of shots from the Aire Valley, south of Skipton, just for the record. By the time the train passed it was over 25 degrees. I hope the aircon in the MkIIs is working!...
