Why couldn't they have put the transformers under the platforms? Could it be the possibly of maintenance, transformer fires, etc. In one of my suggestions to melt snow on platforms, I mentioned using ground source heat pumps. Couldn't the tubes used to extract the heat from the ground be shifted over the transformers to capture the heat generated? Experiments may be needed to see how much heat can be used without blocking ventilation to the vault.
Transformers under the platform would probably cause issues for maintenance and comfort in the summer but running a heat pipe in the platform around local heat sources (like transformers) might be practical from an engineering standpoint.
The big trick here is bureaucracy. Getting two departments to coordinate work at the same time is challenging, as St. Clair experienced, and getting them to work out detailed common design and coordinated maintenance might prove very difficult.
