STANDARDISATION OF WAGONS. SELF-DISCHARGING WAGON WITH GRAVITY UNLOADING DEVICE. PROPOSED STANDARD TYPE

At the joint meeting of the 4th and 5th UIC Commissions in Portsmouth in 1962, the standardization characteristics, proposed by the Sub-Commission on characteristics of standard wagons, was approved for a special 2-axled gravity discharging wagon of about 40 cu m capacity. Two alternatives of this wagon could be constructed, viz., the one with roof and the other without. It was decided to incorporate, in UIC Leaflet 571, a special section dealing with this wagon. The B 12 Specialists Committee was charged by the Control Committ of ORE to study the question of the standard construction of this wagon. The B 12 Specialists Committee had proceeded to an enquiry with those Administrations possessing self-discharging wagons answering to practically all the prescriptions of UIC Leaflet 571 and to the constructional principles employed in the ORE standard wagons. The Committee considered that, in view of their operating characteristics and their mode of construction, the self-discharging wagons of the NS and the DB (constructed moreover by the same firm) could be taken as a suitable basis for the study relating to their standardization. Static compression tests and running performance tests, carried out by the DB, had shown that the constructional features of these wagons were sufficient. It was thus decided to submit to the Control Committee of ORE, by way of prototypes, two self-discharging wagons, one taken from the NS rolling stock (Alternative without roof) and the other from the DB rolling stock (alternative with swing-roof) while requesting the Control Committee to give its approval to these two self-discharging wagons being considered as standard ones.
