97% availability. That's the record of ALCO Century 424's on The Belt of Chicago.

When a railroad handles over 1.9 million cars a year, there’s no time for locomotive downtime. That’s why The Belt Railway Company of Chicago relies on Alco Century’s to handle an important share of their traffic.

Producing 2400 hp for traction, the 424's are The Belt’s most powerful single units. And their heavy weight allows them to develop and utilize their full-rated horsepower throughout their entire operating speed range.

This feature gives The Belt added drag power for heavy loads of coal, while still providing sufficient speed for their transfer operations. Versatility and endurance are built-in features of all Alco Century locomotives. Powered by the proved and improved Model 251 diesel engine, they deliver dependable power for any railroad. Good reason why The Belt has reordered more Century 424's.

But don't take our word for it. Ask any railroader who's in the know on Century motive power. Then contact us for complete data on the full line of Century locomotives. Alco-only domestic manufacturer offering a choice of three power transmission systems: AC, DC and Diesel-Hydraulic.
