The assignment of the B 12 Committee was to define a bogie able to run at 120 km/h, both on standard-gauge (1.435 m) and on broad-gauge (1.524 m) track, which will permit the automatic traction and shock coupler to be used on wagons and which with the aid of some simple intermediate parts could replace the bogie of the present standard flat wagon. The two solutions were proposed: (1) a bogie with super-critical running gear and a suspension system, (2) a bogie with sub-critical running gear, helical springs and vertical and horizontal friction-damping. Testing consisted of: static strength tests, dynamic strength tests, running tests, and removing and mounting tests with the automatic traction and shock coupler. The results obtained with both types of bogie are good. Comparisons of construction and probable maintenance costs of the bogies have not revealed substantial differences. The bogie with leaf springs is 140 kg lighter than with helical springs. Both are lighter than the present standard bogie. In view of the small differences in the quality of each type of bogie, either could be selected as standard.
