It is essential that track design and locomotive design should be considered together as a single joint problem. Present bogie damper designs for both locomotives and coaches must be developed to the stage where they give satisfactory performance for 150,000 miles. Existing carriage brake gear is inadequate for braking from any higher speed than 100 miles/h and has shown itself not to be able to withstand the buffeting which it gets without costly maintenance. Passenger standards for comfort require future stock to be noise-proof and probably, air-conditioned. Studies of sustained higher speed led to several design changes to such things as carriage brakes, the vehicle suspension of both locomotives and carriages, of the overhead contact catenary on electrified lines and so on. They also focused attention upon the importance of the weight, both sprung and unsprung, on the axles of locomotives and the effect their characteristics have on the permanent way and upon its maintenance.
