I think the first 165 to head down the Met tunnel would end up with some rather bent bodywork…
I don’t think this is right.
Years ago I was surprised to read that the flat sided Met line A stock was the widest stock on the whole British Railway.
Wiki confirms that it was 9ft 8 inches or 2.9 metres wide.
A stock was also as tall as BR stock.
The 165s are only 2.85 metres wide.
They are longer than the A stock but their 0.05 metre less width means their throw on the gently curve in the tunnels between Finchley Road & Baker Street will not result in “rather bent bodywork”...unless the 150 daily trips the A stock made for 35 years “down the Met tunnel” resulted in their bodywork twisting & turning on every trip without London Underground knowing!
Posters have given other convincing reasons for the 165s not working to Baker Street but “bent bodywork” is not one of them.
