The Pennsylvania railroad hogan
the testing Of materials In 1878. The
establishment Of the laboratory took
place In 1879, with a force Of only
four men. two on chemical and two
on physical tests. From that time
tho history OF the department has
beer one 81 rapid growth both in
size and importance. until today II is
one 81 the vital parts Of the great
sailroad system. II is sort Of bu-
rcau 81 scientific management where
problems arising daily are studied
oyt. and where infinite time and pains
are expended in working towards the
perfection that means the least waste
and the highest efficiency
