The Southern and Eastern railroads, through their representatives, will explain the present car distribution, the delays in movement and unloading, return of foreign cars to the owning lines, the assessment penalties for misuse of equipment, and measures adopted for securing relief. The shippers charge that railroads receive cars for export without assurance of water shipping facilities, and permit their use for storage. The originating railroad lines claim that their cars are not promptly returned. The Interstate Commerce Commission today prepared a list of questions which they have requested railroads to answer. These ask each line how many of its cars were off its lines on November 1 next: how many foreign cars were on its lines, what efforts made, and results, to have its cars returned; what restrictions it applies to use of equipment; what particular traffic is favored in distribution of cars and why; whether there is any particular traffic that the road feels warranted in giving less than its ratable proportion of available cars, and whether there is any reason to believe that employees are discriminating between shippers in car distribution. Each road is asked whether the present traffic in its territory is abnormal for this season, and to what extent; how much additional equipment would be required to take care of all traffic offered; what percentage of equipment is out of service by reason of not meeting with interchange requirements; what proportion of equipment has been repaired within the past six months to make it fit for service; how many cars have been retired during the past year and how many placed in service.  Or ordered, and when delivery of new cars is expected.
