China's entire high speed network (42000km) was funded on only $900 billion of debt... Yet HS2 is estimated to cost $130 billion and California HSR $128 billion. For comparison, the Beijing-Shanghai high speed rail cost $38 billion (inflation-adjusted) and the Beijing-Tianjin line (China's first HSR) cost about $3.3 billion (inflation-adjusted).

London-Birmingham is a distance of about 160km, Los Angeles-San Francisco is a distance of about 560km, Beijing-Shanghai is a distance of about 1060km, and Beijing-Tianjin is a distance of about 110km (all straight-line).

Edit: another comparison, Japan's Chuo Shinkansen, which is pioneering high-speed maglev technology at scale and involves an absolutely astronomical amount of tunneling, is estimated to cost only $60 billion for 266km.
