Piggy-back Piggy-back

The Big Push

After months of study, the Road decided on May 7 to start piggy-back service on June 16 - just 40 days away.

The decision signaled the start of much activity in many NKP departments, including the Traffic Department, the Transportation Department, the Mechanical Department and the Purchasing Department,. to name but a few.

Rates had to be setup and filed, operating schedules had to be arranged, varied materials had to be bought and cars had to be adapted.

For instance in the Mechanical Department, the personnel had to prepare the flat cars to transport trailers. The engineering group initially decided to follow the pattern used by several western railroads.

Prints of their methods of attachments were obtained. Jacks to support the trailers on the flatcars, tie-down turnbuckles and special castings were ordered. Some special parts were fabricated in the Road's shops at Ironville, and the cars were equipped at Conneaut.

After the Road equipped the six cars, improvements were made on the plans. All wood was removed from the superstructure, and rivets and welds were used to secure the side rub-rails and the hold-downs. This simplified installation and also maintenance, since the new pieces would not deteriorate as rapidly as wooden parts.

Even thought the first test runs showed that the tie-down arrangements were suitable for handling trailers under practically any conditions of railroad service, more improvements now have been developed. They will be used on succeeding cars.

The photographs at the left show the appliances and methods used to secure the trailers on the flatcars for piggy-back service. In the top picture are the jacks, wheel chocks, hold-down fastenings and tools used. In the succeeding pictures Carmen H.J.Stachura and John Rohod are attaching the holddown chains at the front of the trailer, then tightening the screw jacks and lastly applying the hold-down chains at the corners of the trailer.
