Everything has been accounted for. The weight is less than 4 pounds (per locomotive) off, and the fuel tanks are a mear 1 gallon over. There's an engine inside of each locomotive. You can strip off the side panels if you don't believe me. The only two things unwanted here are lettering and interior, because of the part count. Even the horsepower amount is correct.

In 1954, the railroad giant Electro-Motive Division (EMD, a company owned by GE) began production of the General Purpose 9 after the GP7 was introduced. It included more horsepower and survivability than its predecessor. Powering the GP9 was a EMD 567C diesel electric engine, producing 1,750hp at 835RPM, from all 16 cylinders. The use of the GP9 was to solve problems known on the F units, including poor visbility and easily having burnouts.
