Original Note:
Mallard (pictured) holds the world steam speed record of 126mph but reached it only briefly and was damaged by the effort. Its operating speed was around 90mph. HS1 today runs at 186mph with a British speed record of 208mph, although most mainlines are restricted to 125mph. https://en.m.wikipedia.org/wiki/LNER_Class_A4_4468_Mallard https://en.m.wikipedia.org/wiki/Rail_transport_in_Great_Britain
