- A Boy's Wonderful Working Locomotive Model
- A miniature railway locomotive, complete in every detail, which has attracted the attention of the railorad officials of several Pacific Coast lines, is the handiwork of Arthur Johnson, of Portland, Oregon.
- This tin locomotive, only forty-five inches in length, was built to test a new invention of his on a firebox. It is operated by steam, generated by oil fuel, and is equipped with air brakes, an interior throttle and reverse levers and gears.
- The engineering department of the Southern Pacific Company borrowed the model and figured out its weight, power, and all other statistics in the same manner that they would figure on a full-size locomotive. To their surprise they found that the tiny engine developed one-quarter horsepower, and on a level track had a haul capacity of one and a quarter tons.
