The super chargerwill be installed on one of the units for service tests inoperation on the Railways lines. Condition of Motive Power Locomotives in need of repair on the Class I railroadsof this country on November 1 totaled 8,177, or percent of the number on line, according to reports filed bythe carriers with the Car Service Division of the Ameri-can Railway Association. This was a decrease of 429 locomotives compared withthe number in need of repair on October 15. at which timethere were 8,606, or per cent. Locomotives in ne
