Question

LT Northern Line extension from Archway to E. Finchley opened 3 /7/39 which MP cut the 1st sod in Nov 1936?

Answer 1

Since the line is entirely within tunnel, I doubt if there was a first sod to cut. I know you have asked a similar question about the Edgware branch of the Northern Line - what makes you think that an MP was involved in either?

Answer 2

Have a look in the L.T. publication - "100 Years of the Hampstead Tube" and the subsequent editions. All the info is in them +=+
