Very loud blowers on 373 power cars. Sounds like a giant hoover. As an employee, I got invited to the cab by a kind train manager. Walking through the loco, at speed, in a tunnel. Now that is LOUD. With 140mph hurricane coming through the side vents
God that must have been insane, I've been trying to find a video of what it's like to stand in the power car turned on.
Yes that noise was incredible, I only remember seeing 373s from afar, like from down the high-street. But I do remember once when I was a child standing at Hampstead Heath station and a GNER Eurostar came through from North Pole up to Bounds Green. The noise was
overwhelming, I can remember the feeling of it seeming to vibrate in my stomach, will never forget that.
I also remember the North Pole label, and my dad being disgusted in Christmas 1998 that the Hornby model he gave me was a Le Landy "French" set and not a British set.
As for the depot-North Pole was was chosen back in the 70s for the original tunnel proposal, when the intended terminus would have been at White City. Closure of North Pole I think was only decided about 15 years ago. Up until 2004, Waterloo was still intended to be used by Eurostar along with St. Pancras-how I wish it was, the 373 will always be a Southern Region EMU to me!
What fantastic machines they are, I bite my thumb at the 374s
