Single deck subway cars. What happened to them?

[dasatcopthorne]

On another group some has been told by a London Tour Guide that the Subway cars, weren't they F and G, were rebuilt into double decker by stacking one on top of another.

 

I've never heard of this.

 

What is the truth please?

The class F  cars (Nos. 552 - 567) and class G  cars (Nos. 568 - 601) were all "reconstructed" and became the last batch of class E/1 cars (Nos. 552 - 601).  New double deck bodies provided by English Electric Co. Ltd.  were put on the old bogies and the existing electrical equipment was reused.
