A modern signal cabin ...from 1939!

[Mayner]

I was quite taken with the stylish 1930s architecture (and signal boxes) on London Transport and the Southern Region when I first moved to the UK during the mid-80s though professionally I was marginally involved in restoring 4-500 year old buildings in Watford during the construction of the Harlequinn Centre during the late 80s which involved the oblitteration of early-mid 20th Century streetscape.

The GSR signalling and electrical department managed to achieve a lot with very little with the conversion of Kingsbridge Station and Islandbridge-Dunlaoire to power signalling during the 1930s actuated by miniature lever frames fabricated using standard interlocking components housed in quite modernistic signal cabins (Amiens St & Westland Row quite stylish in design).

While the majority of Dublin's  1930s era power signalling system was replaced during the early 80s  in connection with the introduction of the DART, Heuston Cabin 1930s era cabin and signalling system remained in operation until the re-modelling of Heuston Station approaches during the early 2000s.

What was considered modern state of the art during the 1930s was obsolete but sitll functional (if maintained properly) by 2000. As far as I recall control of Heuston and Island Bridge Junction was transferred to a temporary interlocking located in a new building at the Nort end of the  Platform 9 a permanent interlocking installed upon completion for the remodelling of Heuston approaches and the re-instatement of platforms 1-5.
