Stopping from highest speeds requires braking distances such that current ideas and requirements on emergency braking become meaningless; high standards of mental and physical soundness are required of drivers; even so, driver's reaction to lineside signals is too slow, and external control of train speed by lineside detection systems will be required, linked inductively to regulating equipment on train; provided that suitable line of route is available there appears at present to be no precise engineering limitation to attainment of highest speeds on rail which will intervene before cost ceiling is reached at which further increases cannot be justified; there may also be limit to rate at which passengers can contemplate changes of scenery.
