Norfolk and Western yard at Portsmouth, Ohio, is used exclusively for classifying loaded coal cars; automatic switching controls are on teletype tape which is punched for entire train before it is pushed to hump; regrouping of 35 tracks has reduced retarders from 26 to 7 and grade from 0.22% to 0.15, about 45 min being saved for each car.
