“40 years ago
The TIMKEN Bearing was only in its infancy, its use as yet limited to the wheels of horseless carriages. No locomotive engineer would have dared even to dream that such bearings would ever be applied to railroad cars and locomotives…making possible sustained speeds of over 100 miles an hour…with never a hint of a hot box.”
This is a 83 yr. old original vintage ad removed from a 1938 publication and is not a reproduction of any kind.
