How tilting trains suit Britain's curved railways

What are tilting trains, and why are they useful on Britain's existing railways?

They lean into curves so trains can take tighter bends at higher speeds, which suits routes that retain Victorian alignments.

Tilting trains lean into curves so they can run faster on existing railway alignments. That makes them useful on British routes that still follow Victorian curves. The APT-E and APT-P are presented as promising domestic developments that Britain did not carry through. The panel says the technology was sold or transferred abroad, with later development in Japan and Italy, while Britain subsequently bought foreign-built tilting trains. The manufacturer history remains confused in the exchange, so it does not establish a precise chain of ownership.
