Signalling control at Watford high street.

[naz]

I like the photo of the 1938 stock coming into Watford high street station , but as an aside to the subject under discussion here , Can anyone tell me when and how Watford junction PSB took over control of this area. I know there was a separate panel which controlled the bay platforms from 1967 ( not seen any photos of this in original form ) so was the old one extended or was a new longer one put in ?. Also when was the remodelled layout at high street brought into use before or after the signal box closed ?

In my notes I have that Watford Junction No.4 box closed 9/1/67 with new power box opening. Watford High Street box closed 1/11/70 when control went to Watford power box.
