The economic success of the railroads depended on freight shipped in full cars. The idea of putting truck trailers on flatcars was a method of moving less-than-carload shipments economically. This "intermodal" concept held the hope of competing with trucks which were taking more and more of this business from the railroads.

In the mid-thirties, the Chicago, the Great Western and then the New Haven railroads began piggy back service limited to their own railroad. By 1953, the CB&Q, the Eastern Illinois and the Southern Pacific railroads had joined the innovation. Most cars were surplus 50's flatcars equipped with new decks by the railroads. By 1955, an additional 25 railroads had begun some form of piggy back service. A significant legal battle between the truckers and the railroads resulted in a ruling permitting interstate piggy back service using either railroad or privately owned trailers. The stage was set for rapid expansion of intermodal services.


After Trailer-Train incorporated in 1955, they and many other railroads began to build 75 foot cars. Most cities had piggy back facilities. Many small towns had their own ramp for 'circus style' loading. Some of the railroads offering this service were: B&O, CB&Q, CGW, C&EI, C&NW, C&O, DL&W, D&RGW, ERIE, GN, KCS, LV, MDT, Nickleplate, NYC, PENNSY, SF, SP, WABASH and WM.

Another landmark was the introduction of the ACF Model A mechanical hitch in 1956. Until that time, trailers were secured to the flatcars with ropes and other time-consuming tie-down methods. In 1961, the Model 2 hitch was introduced and, later, many other types.

A Brief History of Trailers

Trucks with trailers became a viable transportation business in the 1930's. Early trailers had round noses and were mostly 20 feet long. Box, refrigerator and open top designs with smooth or horizontal corrugated sides were common. Most used only one axle. After World War II, the 35 foot trailers became much more popular with long haul truckers. Flat nose trailers with vertical post sides also were being built in greater numbers. In the early fifties, the round nose trailers were still the most common, but few were being built. In 1958, the 40 foot trailer became legal and most production of long haul trailers switched to this length. Vertical post trailers with flat noses were the most common design, but smooth and corrugated trailers were still being built. This situation remained little changed well into the 70's. Tractors and trailers last for many years and occasionally a short, round nose trailer could still be seen in local service in the 80's.


In the history below are mentions of various "plans" (levels) of TrucTrain service. From actual PRR marketing documents come the following descriptions of the levels:

Plan 1: Railroads and motor common carriers -- PRR carries trailers owned by motor common carriers, on a "division" of the prevailing truck rate -- a flat charge per traler based on weight and distance. The trucker solicits and bills all freight at the truck rates; takes trailers to and from railroad terminals.

Plan 2: A railroad operation, door to door -- PRR carries its own tailers, under its own tarriffs. Under this all-rail plan, the railroad deals directly with shippers; furnishes all equipment; and provides all pick-up and delivery between shipper plants and rail terminals. Pick up and delivery confined to specified territories.

Plan 3: Shipper trailers, rail cars -- PRR carries trailers owned or leased by shippers, at a flat rate. The shipper delivers trailers to railhead; the railroad puts them aboard flat cars, ties them down, transports them to destination and grounds them. The shipper or receiver picks them up at the rail terminal.

Plan 4: Shipper trailers, shipper cars -- PRR carries trailers owned or leased by shippers on cars which are also owned or leased by shippers. Charge is a flat rate per car, whether trailers are loaded or empty. The railroad performs terminal-to-terminal line-haul movement only. Shipper provides drayage at origin and destination.

Plan 5: Joint rates, rail-motor -- PRR carries its own trailers, or common carrier truck trailers, under joint rail-motor rates. In effect it extends the transport operation of each participant into the other carrier's territory, and permits each to sell for the other.

Early Relevant History

As early as 1928, the Pennsylvania Railroad operates short run truck service to coordinate with its LCL (less than car load) service. In the early 1950's this service is upgraded and dubbed "Keystone Merchandise Service".

Per Chris Baer: "Excelsior Truck Leasing Company was incorporated in Delaware on 8/18/1953 for the purpose of owning and leasing trailers to PRR for TrucTrain service. On 2/1/1954 it absorbed Scott Truck Leasing Company and Penntruck Leasing, Inc. It was controlled by the PRR through the American Contract & Trust Company, later American Contract Company, and lasted long enough to become a Conrail subsidiary in 1976."

January 30, 1950

kmsPRR announces introduction of "Keystone Merchandise Service" for LCL freight, including 500 special new box cars, 3,000 containers and expanded truck pick-up-and-delivery service; will restore speed of freight trains to prewar levels. Partly a response to NYC's "Pacemaker Service" introduced in 1946.

April 24, 1950

PRR establishes second morning service for LCL and freight forwarders, New York-Chicago and New York-East St. Louis; establishes new LCL-2 (Chicago-Harsimus Cove), LCL-3 (Harsimus Cove-East St. Louis) and LCL-4 (East St. Louis-Pitcairn); revises operation of LCL-1 and drops old LCL-2 (Pittsburgh-Harsimus Cove) and LCL-3 (Enola-Chicago); all new freights are diesel powered.

June 1954

The Pennsylvania Railroad announces its new trailer on flat car (TOFC) service to its customers with the brochure "Quick Facts about the New Rail Highway Trailer Service". The service is initially called "Pennsy Rail Trailer Route", but a contest to formally name the new service is announced to employees.

115 flat cars of Class F30d, built in 1951, are converted for use in TOFC service. These 50' cars can each hold one trailer.

24trailerExisting LCL service 24' to 26' trailers will be used in the new TOFC service. These trailers have smooth or ribbed sides, a rounded front end, and a curb side door. The trailers feature the text "PENNSYLVANIA RAILROAD" running diagonally from lower left to upper right. At each end of the text is a keystone logo with the text "KEYSTONE MERCHANDISE SERVICE" inside. Elsewhere on the trailer sides is the text "DOOR TO DOOR SERVICE" and "PICKUP AND DELIVERY". By the early 1950's, over 8,600 tractors and trailers are in service.

The Pennsy leases 150 new 30' Fruehauf trailers for the new service. Lettering is the same, but the text inside the keystone logo is replaced by "PRR". Like earlier trailers, they had one axle.
