Why Gare Loch was not industrialised more heavily

Why was Gare Loch not industrialised and militarised more heavily during the railway boom?

Other facilities already existed, and limited money, time, and construction capacity were committed elsewhere.

A viewer asks why Gare Loch was not more heavily industrialised and militarised during the railway boom. Useful alternatives were already in place elsewhere. Governments and firms had only so much money, time, and construction capacity to distribute among competing sites. Gare Loch might have received more work if an investor or state sponsor had committed those resources, but no such programme followed. Suitable geography created an option, while investment decisions determined whether it became a functioning naval base.
