High speed running tests, Cheddington, 1970 measurement of track forces at a dipped rail joint (E-658)

Proposed increases in main-line running speeds, first to 110 m.p.h. with existing locomotive types and subsequently to 125 m.p.h. with new, yet conventional designs pose a number of questions of mechanical, electrical and aerodynamic performance. An important consideration is the possibility of very high loads being induced in the track...
