The long running project by multiple parties to re-signal the Toronto Terminal Railway, aka Union Station Rail Corridor in Canada is showing progress in the form of new signal bridges going up between SCOTT ST and CHERRY ST interlocking towers. Those, along with JOHN ST comprised the signaling control infrastructure that went in with Toronto Union Station in 1927. The large GRS supplied plant made use of Model 5B pistol grip type interlocking machines in the style of Buffalo Central Station.

While the 1927 dwarf searchlights are still in place it is unclear what exactly will replace them. The new signal gantries are equipped with LED searchlights so my assumption is that there will be some manner of LED dwarfs in the station, but there are still a number of possible configurations and vendors.
You can see in the photos below the new signal bridges. You can also see that the GRA Model 5A point machines have been replaced by a US&S M3 derivative.
We have seen examples of these new LED searchlights elsewhere on Canadian railroads.
Google Street View is also fairly useful here with the new giant signal bridges being equipped with 3-head high signals, which is on par with Canadian practice. If they will display anything better than slow speed indications is another question.
Another interesting tidbit is that the CHERRY ST tower got a full rehab in 2021.
Anyway if you are Canadian it might be a good idea to get down to Union Station and get as many photos of the old interlocking plant as possible.
